Answer:
Simplifying
4x + 9 = 12x + -3
Reorder the terms:
9 + 4x = 12x + -3
Reorder the terms:
9 + 4x = -3 + 12x
Solving
9 + 4x = -3 + 12x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12x' to each side of the equation.
9 + 4x + -12x = -3 + 12x + -12x
Combine like terms: 4x + -12x = -8x
9 + -8x = -3 + 12x + -12x
Combine like terms: 12x + -12x = 0
9 + -8x = -3 + 0
9 + -8x = -3
Add '-9' to each side of the equation.
9 + -9 + -8x = -3 + -9
Combine like terms: 9 + -9 = 0
0 + -8x = -3 + -9
-8x = -3 + -9
Combine like terms: -3 + -9 = -12
-8x = -12
Divide each side by '-8'.
x = 1.5
Simplifying
x = 1.5

Answer:
2414.42 cm^2
Step-by-step explanation:
volume = base x height
and we know that a cube will always have the same length for any side so volume is basically length^3
volume = length^3
8073 = x^3
x = ![\sqrt[3]{8073}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8073%7D)
use a calculator and you get that x = 20.06 cm
Surface area(SA) = 6a^2 (a is area)
a = x^2
so SA = 6(20.06)^2 = 2414.4216 ≈ 2414.42 cm^2

Answer:
Not sure what this question is asking but for the hourly rate, the answer is $20.
Step-by-step explanation:
You can write an equation as 20x=400.
Simply solve it by dividing each side by 20 to find the hourly rate in dollars per hour.
You get x=20 as your answer so 20 dollars per hour!
Hope this helps! :)
