Answer:
Whenever you divide two terms with the same base, you keep the base and subtract the exponents.
Example:
x³ / x⁷ = x³⁻⁷ = x⁻⁴ = 1 / x⁴
or
8¹³ / 8⁶ = 8¹³⁻⁶ = 8⁷
Whenever you multiply two terms with the same base, you keep the base and add the exponents.
Example:
x³ × x⁷ = x³⁺⁷ = x¹⁰
or
12⁻⁵ × 12⁹ = 12⁻⁵⁺⁹ = 12⁹⁻⁵ = 12⁴

1. (08.01, 8.02 MC) An expression is shown below: 2x3y2 + 18xy2 − 20x2y − 180y Part A: Rewrite the expression so that the GCF is factored completely. (4 points) Part B: Rewrite the expression completely factored. Show the steps of your work. (6 points) (10 points)
Answer:
A. 2y
B. (xy − 10)(2x²y + 18y)
Step-by-step explanation:
Part A: Rewrite the expression so that the GCF is factored completely.
2x³y² + 18xy² − 20x²y − 180y
Factoring y out, we have
(2x³y + 18xy − 20x² − 180)y
Factoring 2 out, we have
(x³y + 9xy − 10x² − 90)2y
So, the GCF is 2y and the expression factored is (x³y + 9xy − 10x² − 90)2y
Part B: Rewrite the expression completely factored.
2x³y² + 18xy² − 20x²y − 180y
Rearranging, we have
2x³y² − 20x²y + 18xy² − 180y
Separating them into brackets, we have
(2x³y² − 20x²y) + (18xy² − 180y)
Factorizing the expressions in bracket, we have
(xy − 10)2x²y + (xy − 10)18y
collecting like terms, we have
(xy − 10)(2x²y + 18y)
Mr. Carlevato and Mr. Burrows get into a debate about two different expressions. · Mr. Carlevato says "2(2x + 3) is equal to 4x + 6". · Mr. Burrows says "Nope, wrong, those are clearly different expressions" Try substituting x=5 into both expressions. Do you get the same answer for both expressions? Show your work!
Answer:
Yes, the same answer is obtained.
Step-by-step explanation:
According to Mr. Carlevato, [tex]2(2x+3)[/tex] is equal to [tex]4x+6[/tex]. However, [tex]2(2x+3)[/tex] is not equal to [tex]4x+6[/tex] according to Mr. Burrows.
Put [tex]x=5[/tex] in [tex]2(2x+3)[/tex]
[tex]2[2(5)+3]=2(10+3)=2(13)=26[/tex]
Put [tex]x=5[/tex] in [tex]4x+6[/tex]
[tex]4x+6=4(5)+6=20+6=26[/tex]
Therefore,
[tex]2(2x+3)=4x+6[/tex]
Yes, the same answer is obtained.

What is 3 (2x + 4) = 12?
Answer:
Hi!!
The answer is = 0
Step-by-step explanation:
1. Distribute
3(2+4)=12
6+12=12
2. Subtract 12 from both sides of the equation
6 + 12= 12
6 + 12 − 12 = 12 − 12
3.Simplify
part A. 6 + 12 − 12 = 12 − 12
6x = 12 - 12
part B. 6x = 12 - 12
6x = 0
Hope this helps!! =)

Find the volume of the Cone. Use 3.14 for . Round your answer to the nearest hundredth ( 2 decimals). Show your work in this question, and record your answer in the next question.
Answer:
2,616.67cm³
Step-by-step explanation:
Find the diagram attached
volume of the cone = πr²h/3
r is the radius = 10cm
h is the height = 25cm
Substitute
V = 3.14(10)²*25/3
V = 314*25/3
V = 7850/3
V = 2,616.67cm³
Hence the volume of the cone to the nearest hundredth is 2,616.67cm³
Find the solutions to x2 = 8.
A. X = +2.2
B. x= 12,4
C. X = +4-2
D. = +4.6
Answer:
x = ± 2√2
Step-by-step explanation:
Assuming "x2" is x^2 or "x squared", the answer can be derived from "square-rooting" both sides.
√ x^2 = √ 8
Then we simplify.
x = ± 2√2

Is -1-126
(-12b - 6 + 9b - 18) equivalent to 2(b + 8)? Show your work.(please help)
Answer:
Well, -1-126 (-12b - 6 + 9b - 18) equals 378b + 2023.
Step-by-step explanation:
Subtract numbers:
−1−126 (−12−6+9−18)
−1−126 (−12−24+9)
Combine like terms:
−1−126 (−12−24+9)
−1−126 (−3−24)
Then you'll have to distribute:
−1−126 (−3−24)
−1+378 + 3024

Answer:

Step-by-step explanation:
To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.
To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.
Hope this helps! Thanks for brainliest! :D
