300 dollars, 15x20 because they count any fraction as a foot, so is like you are going to buy 20 foot of carpet.
Answer:
Step-by-step explanation:
4a² b³ * (9a⁴b² - 4a² + 3) = 4a²b³ * 9a⁴b² - 4a²b³*4a² + 4a²b³*3
= 36a²⁺⁴ b³⁺² -16a²⁺²b³ + 12a²b³
= 36a⁶b⁵ - 16a⁴b³ + 12a²b³
So if you wanted the factored form (exg. 1*2*3*4=24)
then this is (5 times 5 times 7)
