Answer:
See the first 3 problems solved below.
I added the next 3 problems.
Step-by-step explanation:
1.
2x + 4x = 180
6x = 180
x = 30
2x = 2(30) = 60
4x = 4(30) = 120
2.
3x + 6x = 180
9x = 180
x = 20
3x = 3(20) = 60
6x = 6(20) = 120
3.
8x + 10x = 180
18x = 180
x = 10
8x = 8(10) = 80
10x = 10(10) = 100
4.
7x + 8x = 180
15x = 180
x = 12
7x = 7(12) = 84
8x = 8(12) = 96
5.
2x + x = 180
3x = 180
x = 60
2x = 120
6.
2x + 2x = 180
4x = 180
x = 45
2x = 2(45) = 90

Answer:
C.
Step-by-step explanation:
= ![\sqrt[3]{8}^{x}\\](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%5E%7Bx%7D%5C%5C)
= Since ![\sqrt[3]{} = ^{1/3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%7D%20%3D%20%5E%7B1%2F3%7D)
= So, It becomes :
= ![8^{\frac{x}{3}](https://tex.z-dn.net/?f=8%5E%7B%5Cfrac%7Bx%7D%7B3%7D)
The answer would be True. It passes the vertical line test
Answer:
Length: 40 inches
Width: 10 inches
Step-by-step explanation:
Let
width of the rectangle.
From the information "length of a rectangle is four times its width", we can express the length as:
Length = ![4x](https://tex.z-dn.net/?f=4x)
- - - -
Perimeter =
(formula for perimeter of rectangle)
![100=2(4x)+2(x)](https://tex.z-dn.net/?f=100%3D2%284x%29%2B2%28x%29)
![100=8x+2x](https://tex.z-dn.net/?f=100%3D8x%2B2x)
(combine like terms)
inches
∴ The width of the rectangle is 10 inches.
To find the length of the rectangle, we can use substitution:
Length = ![4x](https://tex.z-dn.net/?f=4x)
![=4(10)](https://tex.z-dn.net/?f=%3D4%2810%29)
inches
∴ The length of the rectangle is 40 inches.
Hope this helps :)
