Step-by-step explanation:
5 friends each have 3 brownies
you want to take 5 and multiply it by 3
5x3=15
15 brownies were in the box
Answer:subtract 9 3 times, then subtract 4 and add 1
64-55=9
a = 2x, b = 3.
8x^3+27 = (2x)^3 + 3^3
a = 2x and b = 3.
We can cube root 8x^3 getting 2x and cube root 27 getting 3.
