Factor –7x3 + 21x2 + 3x – 9 by grouping. What is the resulting expression?
(3 – 7x)(x2 – 3)
(7x – 3)(3 + x2)
(3 – 7x2)(x – 3)
(7x2 – 3)(3 + x)
Answer:
(3–7x²)(x–3)
Step-by-step explanation:
If you apply the distributive property in (3–7x²)(x–3), you obtain:
3x-9-7x²(x)+21x²
3x-9-7x³+21x²
When you order the expression, you have:
-7x³+21x²+3x-9
Then, the answer is (3–7x²)(x–3)
The resulting expression from the given algebra after grouping is; C: (3 – 7x²)(x – 3)
What is the resulting algebra expression?We want to simplify the algebraic expression; -7x³ + 21x² + 3x - 9
Applying distributive property of algebra, we have;
-7x²(x - 3) + 3(x - 3)
By factorization, we have;
(3 – 7x²)(x – 3)
Looking at the options, only option C is correct

Answer:
Step-by-step explanation:
8x-9+2+9x=180 degree(being co interior angles)
17x-7=180
17x=180+7
x=187/17
x=11 degree
Answer:
11
Step-by-step explanation:
consecutive interior angles always equal to 180 degrees, so you would add both equations together and equal it to 180 degrees. you would then simplify and solve.
8x-9 + 2+9x = 180
-7 + 17x = 180
-7+7 180+7 = 187
17x = 187
17x/17 = 187/17
x=11

The volume of a pyramid that fits exactly inside a cube is 10 cubic feet. What is the volume of the cube? (5 points)
30 cubic feet
100 cubic feet
300 cubic feet
1000 cubic feet
Answer:
30 cubic feet
Step-by-step explanation:
volume of a pyramid is (l*w*h)=3
assuming it is a pyrmaid where l=w=h, volume = x^3/3 = 10
x^3=30
x=30^(1/3)
volume of a cube is l*w*h, with our assumption, that translates to x*x*x
Volume = 30^(1/3)*3 = 30 cubic feet
The volume of the cube, in relation to the given pyramid is: 30 cubic feet.
What is a Cube?Volume of a pyramid = 1/3(l × w × h)Volume of a cube = l × w × hRelating both volumes, we would have:
Volume of cube = 3(volume of pyramid)
Volume of pyramid is given as 10 cubic feet, therefore:
Volume of the cube = 3(10)
Volume of the cube = 30 cubic feet.

Explanation:
8 jars need 1.8 kg of caster sugar.
Cut each value in half to see that 4 jars need 0.9 kg of caster sugar.
Convert 0.9 kg to grams to get 900 grams (multiply by 1000 to go from kg to grams).
Jayne needs 900 grams of caster sugar. She has 860 grams already, which means she needs an additional 900-860 = 40 grams
If you were to pick one day of the year at random, is it more likely that the day would be a Tuesday or that the day would fall during the month of January?
Answer and explain in your own words why you chose what you chose.
Answer: It's more likely it's a Tuesday
========================================================
Explanation:
The odds of it being a Tuesday is 1/7 since there's 1 day of the week that's Tuesday out of 7 total.
The odds of it being January is 1/12 because we have 1 month we want out of 12 total.
Now the question is: which fraction is larger?
For now, assume they are equal. We'll cross multiply like so
1/7 = 1/12
1*12 = 7*1
12 = 7
We get a false statement at the end, but we can fix things by replacing the equal sign with a greater than sign to get this new set of steps
1/7 > 1/12
1*12 > 7*1
12 > 7
which leads us to a true statement. Therefore, 1/7 is the larger fraction and the more likely event.
-----------------
Alternatively, you can use your calculator to find that:
1/7 = 0.143 approximately1/12 = 0.083 approximatelyThen for each decimal, move the decimal point 3 spots to the right. The values 0.143 and 0.083 become 143 and 83 respectively. We can see that 143 is larger, which means 0.143 is larger, and lastly 1/7 is larger. Think of it like a chain.

The area of the room is 147.5 square feet so Michelle's reasoning was incorrect.
Step-by-step explanation:
Step 1:
To calculate the area of the given room, we divide the unknown shape into known shapes.
The room's shape is made of 2 rectangles.
The area of a rectangle is the product of its length and its width.
One rectangle has a length of 10 feet and a width of 12 1/2 feet.
The other rectangle has a length of 15 - 10 = 5 feet and a width of 4 1/2 feet.
Step 2:
The area of the first rectangle = (10)(12 1/2) = (10)(12.5) = 125 square feet.
The area of the second rectangle (10)(4 1/2) = (5)(4.5) = 22.5 square feet.
The total area of the room = 125 + 22.5 = 147.5 square feet.
Answer:
147.5ft²
Step-by-step explanation:
10 × 12¹/₂ = 125
5 × 4¹/₂ = 22¹/₂
Total area = 125 + 22¹/₂
Total area = 147¹/₂ = 147.5

Help Pls. Find the radius of Circle Q.
The radius of the given circle is 13 unit.
What is a chord of a circle?
The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.
What is radius of a circle?A radius is a measure of distance from the center of any circular object to its outermost edge or boundary.
What is Pythagoras theorem?Pythagoras theorem states that "the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides".
According to the given question
We have a circle with center Q and two chords AD and BC.
And, AD = 4x + 4 and BC = 6x -6
Since, both the chords are at the same distance from the center of the circle, so their lengths will same.
⇒ AD = BC
⇒ 4x + 4 = 6x -6
⇒ 4 + 6 = 6x -4x
⇒ 10 = 2x
⇒ x = 5
Therefore,
AD = 4x + 4 = 4(5) + 4 = 20 +4 =24
and, BC = 6x - 6 = 6(5) - 6 = 30 -6 = 24
Also, AP = AD/2 = 24/2 = 12
Now, in right angle triangle QPA we have
[tex]AQ^{2} =QP^{2} +AP^{2}[/tex] ( By Pythagoras theorem)
⇒ [tex]AQ^{2} = 5^{2} +12^{2}[/tex]
⇒[tex]AQ^{2} = 25 + 144[/tex]
⇒[tex]AQ^{2} = 169[/tex]
⇒[tex]AQ =\sqrt{169}[/tex]
⇒ AQ = 13
Hence, the radius of the given circle is 13 unit.

Class A has 12 pupils and class B has 29 pupils.
Both classes sit the same maths test.
The mean score for class A is 52.
The mean score for both classes is 24.
What is the mean score (rounded to 2 DP) in the maths test for class B?
Answer:
The mean score in the maths test for class B was 12.41 points.
Step-by-step explanation:
Given that Class A has 12 pupils and class B has 29 pupils, and both classes sit the same maths test, and the mean score for class A is 52 while the mean score for both classes is 24, to determine what is the mean score in the maths test for class B the following calculation must be performed:
52 x 12 + X x 29 = 24 x (12 + 29)
624 + 29X = 24 x 41
624 + 29X = 984
29X = 984 - 624
X = 360/29
X = 12.41
Therefore, the mean score in the maths test for class B was 12.41 points.
The number of Roberto’s baseball cards is ¾ the number of David’s cards If Roberto gives ½ of his cards to David, what will be the ratio of Roberto’s cards to David’s cards? please help me. I need it to step by step equations!!!!
Answer:
1/4, 0.25
Step-by-step explanation:
Answer:
3/11
Step-by-step explanation:
Let Roberto's cards be x.
Let David's cards be y
x = (3/4) y
Roberto gives half his cards away which is 1/2*(3/4) = 3/8
David's new amount after the gift = 1/2(3/4)y + y = 3/8y+y=3y/8+8y/8 = 11y/8
So the ratio is Roberto / David = (3/8) // (11/8)
Roberto to David = 3/8 // 11.8 which you now invert and multiply the denominator
Roberto to David = 3/8 * 8/11 = 3/11
