Answer:
x² + 2x - 6
Step-by-step explanation:
= f(x) + g(x)
= (2x + 1) + (x² - 7)
= 2x + 1 + x² - 7
= 2x - 6 + x²
= x² + 2x - 6

In trapezoid MNPQ shown below, MN || QP, m&M = 108°, m&P = 4x - 5, and
mxQ = 3x + 21. What is the number of degrees in m«N.
Answer:
Answer:
The answer is below
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base. Also, the angles on the same leg of a trapezoid (adjacent angles) are supplementary (add up to 180°).
In trapezoid MNPQ:
∠M + ∠Q = 180° (angles on the same leg are supplementary)
108 + (3x + 21) = 180
3x + 129 = 180
3x = 51
x = 17
Also:
∠N + ∠P = 180° (angles on the same leg are supplementary)
∠N + (4x - 15) = 180
∠N = 180 - (4x - 15)
∠N = 180 - 4x + 15
∠N = 195 - 4x
substitute x = 17°:
∠N = 195 - 4(17)
∠N = 127°
If a man walks at the rate of 3 feet per second, how many minutes will it take him to walk 5760 feet?
Answer:
32 minutes
Step-by-step explanation:
There are 60 seconds in a minute
That means we will need to know how many feet he walks in a minute
So we would do 3 x 60 which equals 180 so he walks 180 ft per miute
Now we need to figure out how many minutes it took for him to walk 5760 ft.
So we would do 5760 ÷ 180 which equals 32
So the aswer is 32 minutes for him to walk 5760 ft.
Hope this helps
Please help thank you
Answer:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
There were 140 geese living in Larson Lake last year. It is overpopulated. A scientist has suggested a program to decrease the population of geese by 15% after 5 years. How many geese does the scientist hope will be in the lake in 5 years? Show your work.
Answer:
119
Step-by-step explanation:
Find 10% by dividing by 10, then halve it to get 5%. The answers are 14 and 7 accordingly.
Add them together to get 15%, which is now 21.
Take 21 off of 140 to get the answer, which is 119.

What will be the area of this parallelogram?
Include the appropriate unit in your answer.
Answer:
13.75 square feet
Step-by-step explanation:
all you have to do to find the area of a parallelogram is base * height
= 2.5 * 5.5
= 13.75 square feet
Answer:
13.75 ft^2
Step-by-step explanation:
I) Substitute equation to find the area
a = hb (area = height x base)
a = 2.5(5.5)
II) Solve:
a = 2.5(5.5)
a = 13.75
The area is 13.75 ft^2.

Answer:
5
Step-by-step explanation:
First, find the equation of the line:
put it in the form y = mx + b where m is the slope and b is the y-intercept
You already have m = 2, so y = 2x + b.
Then, since you know (1, 3) is a solution so you can plug x = 1 and y = 3 into the equation to find out what b is.
3 = 2 * 1 + b
3 = 2 + b
1 = b
This means the equation of the line is y = 2x + 1.
Then, since you're trying to find out what y is when x = 2, you can plug in x = 2 into the equation:
y = 2 * 2 + 1
y = 4 + 1
y = 5
5 is the answer

Answer:
12. median: AD; altitude: CE; midsegment: none
13. x = 2
Step-by-step explanation:
12. The median joins a vertex with the midpoint of the opposite side. Point D is identified as the midpoint of BC, so AD is the median.
An altitude is a segment from a vertex that is perpendicular to the opposite side. CE is an altitude of this triangle.
A midsegment joins midpoints of adjacent sides of the triangle. Only one midpoint (D) is identified in this triangle, so no midsegment can be named.
Additional comment: BF is an angle bisector. Perhaps that is what is intended in part (c). You may want to report this question to your teacher.
__
13. The base segment is twice the length of the midsegment:
2(5x -3) = x +12
10x -6 = x +12 . . . . . eliminate parentheses
9x = 18 . . . . . . . . . . add 6-x
x = 2 . . . . . . . . . . . . .divide by 9

How many degrees are there in the "Department Store" angle? *
How many degrees are there in the "Gas Station" angle? *
Answer:
Department Store:
7(18.75)+8= 139.25
Gas Station:
18.75+22= 40.75
Step-by-step explanation:
The mistake is 7x+8+x+22 should not equal 90. It should equal 180 degrees because the two angles are supplementary angles. (It forms a straight line)
Correct equation and how to solve for X:
7x+8+x+22=180
8x+30= 180
8x= 150
x=18.75
Department Store:
7(18.75)+8= 139.25
Gas Station:
18.75+22= 40.75

the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter reprecents 20 kilometers. what is the actual distance between these two cities in kilometers?
Answer:
70 kilometers
Step-by-step explanation:
Set up a proportion where x is the actual distance
[tex]\frac{1}{20}[/tex] = [tex]\frac{3.5}{x}[/tex]
Cross multiply:
x = (20)(3.5)
x = 70
So, the actual distance is 70 km
