x³+ax²+bx+6 has (x-2) as factor and leaves remainder 3 when divided by (x-3), find values of a and b
Explanation:
this is your answer....
P(x) = x^3 + ax^2 + bx + 6
________________________________
Reminder :
x - a = 0 ==》 x = a
P(a) = Reamaining of the diving P(x) by
( x - a )
________________________________
x - 2 = 0 ==》x = 2 ==》P(2) = 0
(2)^3 + a(2)^2 + b(2) + 6 = 0
8 + 4a + 2b + 6 = 0
4a + 2b + 14 = 0
4a + 2b + 14 - 14 = 0 - 14
4a + 2b = - 14
( 4a + 2b ) ÷ 2 = ( -14 ) ÷ 2
2a + b = - 7 ( ♡ )
_________________________________
x - 3 = 0 ==》 x = 3 ==》P(3) = 3
(3)^3 + a(3)^2 + b(3) + 6 = 3
27 + 9a + 3b + 6 = 3
9a + 3b + 33 = 3
9a + 3b + 33 - 33 = 3 - 33
9a + 3b = - 30
( 9a + 3b ) ÷ 3 = ( - 30 ) ÷ 3
3a + b = - 10 ( ☆ )
________________________________
( ♡ ) , ( ☆ ) in pair system of equation
( ☆ ) : 3a + b = - 10 3a + b = - 10
====》
( ♡ ) : 2a + b = - 7 × (-1) - 2a - b = + 7
___________ +
a = - 3
So :
2( - 3 ) + b = - 7
- 6 + b = - 7
- 6 + 6 + b = - 7 + 6
b = - 1

Answer:
m< B = 120°
Explanation:
The sum of the angles of a trapezoids 360°
m<c=m<D= 60°
60°+60°+2x=360°
120°+2x=360°
2x=360°–120°
2x=240°
x=240/2
x=120°
So : m<B =120°
2. Why did the Nazis want to restrict the amount of money a Jewish family could have in their possession? For what purposes did Jewish families hide their money?
Answer:
Hitler and the Nazis carried out this policy mainly for two reasons:
Antisemitism: the first reason is simply anti-Semitism. The Nazis hated the Jewish people, they believed that they had too much economic power, and that this power should be reduced.The need for funds: the main economic goal of the Nazis was to boost the German economy in order to finance a powerful military that would take over most of Europe. To achieve this goal, the Nazis needed every possible source of income at their disposal. and the wealth of individual Jewish families was not an exception to this.Jewish families hid their money simply because they knew that otherwise it would be taken away from them. They also had important amounts of wealth invested in the form of equity because economy stocks are harder to confiscate than economy flows.

An archaeologist found some maps made by an ancient civilization. Which ancient map would be the most likely to show local trade routes
Answer:
A thematic map would be more likely to show local trade routes.
Explanation:
Thematic maps represent the terrestrial surface, taking into account some specific element. Thus, thematic maps, in addition to presenting the physical characteristics of the region, can present elements capable of facilitating the reading of the map and presenting more information to the observer. In this way, a thematic map can show the location of monasteries, forests and even trade routes.
In this case, we can consider that a thematic map would probably present local commercial routes.

Which of the following potential solutions could help a crowded city improve its management of water supplies?
A.
encourage citizens to conserve water in their homes
B.
allow unregulated dumping in rivers and creeks
C.
encourage citizens to grow water-intensive crops
D.
help citizens use more water on agricultural crops
Please select the best answer from the choices provided.
A
B
C
D
Answer:
I'm pretty sure that the answer is B
Explanation:
mostly because if your trying to make solutions that could help a crowded city improve its management of water supplies you wouldn't want unregulated dumping in rivers and creeks or help citizens use more water on agricultural crops and encouraging citizens to grow water-intensive crops is the same thing as the other but not all people have crops.
Answer:
A. encourage citizens to conserve water in their homes.
Explanation:
Conservation of water would definitely help to manage water supplies. It's the most appropriate answer. Also, It is correct on edg.
Find the perimeter of a quadrilateral with vertices at C (−2, 4), D (−3, 1), E (1, 0), and F (−1, 2). Round your answer to the nearest hundredth when necessary.
10 units
10.77 units
11.52 units
12.35 units
Answer:
Perimeter of quadrilateral = 12.35 units
Explanation:
To find - Find the perimeter of a quadrilateral with vertices at C (−2, 4), D (−3, 1), E (1, 0), and F (−1, 2).
Proof -
The figure becomes :
We have the points -
C (−2, 4),
D (−3, 1),
E (1, 0),
F (−1, 2)
Now,
We know that -
The perimeter = Distance of (CD + DE + EF + FC)
Now,
Distance of CD = √(-3 + 2)² + (1 - 4)²
= √(-1)² + (-3)²
= √1 + 9
= √10 = 3.16
⇒Distance of CD = 3.16
Now,
Distance of DE = √(1 + 3)² + (0 - 1)²
= √(4)² + (-1)²
= √16 + 1
= √17 = 4.12
⇒Distance of DE = 4.12
Now,
Distance of EF = √(-1 - 1)² + (2 - 0)²
= √(-2)² + (2)²
= √4 + 4
= √8 = 2.83
⇒Distance of EF = 2.83
Now,
Distance of FC = √(-2 + 1)² + (4 - 2)²
= √(-1)² + (2)²
= √1 + 4
= √5 = 2.24
⇒Distance of FC = 2.24
So,
Perimeter of quadrilateral = 3.16 + 4.12 + 2.83 + 2.24
= 12.35 units
⇒Perimeter of quadrilateral = 12.35 units
Based on the information given, the perimeter of the quadrilateral will be 12.35 units.
Calculating the perimeter.From the information given the distance of CD will be:
= ✓1 + ✓9
= 3.16
The distance of DE will be:
= ✓16 + ✓1
= 4.12
The distance of EF will be;
= ✓4 + ✓4
= 2.83
The distance of FC will be:
= ✓1 + ✓4
= 2.24
Therefore, the perimeter will be:
= 3.16 + 4.12 + 2.83 + 2.24
= 12.35 units

WHY IS FAST FOOD SO POPULAR? And how does this relate back to Human Geography? Please ANSWER BOTH PARTS!
1.Ok fast food is popular because its cheap and it does not cost as much as a fancy restaurant. And it's not like it has a bad taste to it it taste good but however the cheaper it is the cheaper it taste.
2.The availability of food high in fat, salt and sugar through Fast Food (FF) or takeaway outlets, is implicated in the causal pathway for the obesity epidemic. This review aims to summarise this body of research and highlight areas for future work. Thirty three studies were found that had assessed the geography of these outlets. Fourteen studies showed a positive association between availability of FF outlets and increasing deprivation. Another 13 studies also included overweight or obesity data and showed conflicting results between obesity/overweight and FF outlet availability. There is some evidence that FF availability is associated with lower fruit and vegetable intake. There is potential for land use policies to have an influence on the location of new FF outlets. Further research should incorporate good quality data on FF consumption, weight and physical activity.

Maritime air masses form _____.
over land
only in summer
only in winter
over water
Maritime air masses form over water. Thus, option 4th is correct.
What are maritime tropical air masses?Maritime tropical (mT) air masses are often warm, wet, and unstable. Certain maritime tropical air masses form in the equatorial Pacific Ocean, where temperatures are high and air must travel a considerable distance over the sea.
Maritime air masses are humid and originate over water. Dry continental air masses form over land. As a result, an air mass that forms over northern Canada is known as a continental polar air mass, and it is cold and dry. A marine tropical air mass develops over the Indian Ocean and is warm and humid.
Maritime tropical air masses form over the warm seas of the tropics and the Gulf of Mexico, where heat and moisture from the waters below are transmitted to the overlying air. The migration of tropical air masses northward delivers warm wet air into the United States, increasing the possibility of precipitation. Hence, option 4th is correct.

A.
increased production
B.
reduced costs of consumer goods
C.
increased farm employment
D.
the invention of new products
the answer is c.
Answer: B
Explanation:
The technological and industrial history of the United States describes the United States' emergence as one of the most technologically advanced nations in the world. The availability of land and literate labor, the absence of a landed aristocracy, the prestige of entrepreneurship, the diversity of climate and large easily accessed upscale and literate markets all contributed to America's rapid industrialization. The availability of capital, development by the free market of navigable rivers and coastal waterways, as well as the abundance of natural resources facilitated the cheap extraction of energy all contributed to America's rapid industrialization. Fast transport by the very large railroad built in the mid-19th century, and the Interstate Highway System built in the late 20th century, enlarged the markets and reduced shipping and production costs. The legal system facilitated business operations and guaranteed contracts. Cut off from Europe by the embargo and the British blockade in the War of 1812 (1807–15), entrepreneurs opened factories in the Northeast that set the stage for rapid industrialization modeled on British innovations.
