The answer should be 4x^2-x+9
which means the answer is A.
We can use the formula: V = (1/3)a2h to solve this (a is not area, it’s for side length
We plug in our variables
V=(1/3)10^2x12
We get the answer 400m^3
Solidify the W then do the rest of the problem
the answer should be the W
1.) 243.56 2.) 7.608 3.) 92.0011
earnings * 20 percent = 17
earnings * .2 = 17
divide by .2 on each side
earnings = 17/.2
earnings = $85.00
