Answer:
x=-11
Step-by-step explanation:
211.75
179.99/.85=211.75
x has to be greater or equal to 16,000
x ≥ 16,000
45 cm^2
The formula you have written in pencil is correct.
Area = B*H
B = 9
H = 5
Area = 5*9
Area = 45 cm^2
, where s is the side length. Then, just do 9 to the third power, or 9*9*9, which equals 729.
