The formula for this is

. Filling in accordingly,

. This simplifies to

and 36=6x. Therefore, x = 6 so the bases are 6 and 12.
The rent for one book for one week is thirteen dollars and thirty-three cents.
(3x³ - 7x² + 12) - (3x³ + 6x² + 10x)
(3x³ - 3x³) + (-7x² + 6x²) - 10x + 12
-x² - 10x + 12
Answer:
x= 11.66667
Step-by-step explanation:
ok the six is repeating but, basically multiply 5 times 7, then divide that by 3
