The volume of the first cube is (5h^2)^3, while the volume of the second cube is (3k)^3, so their total volume is (5h^2)^3 + (3k)^3. We can use the special formula for factoring a sum of two cubes:
x^3 + y^3 = (x + y)(x^2 - xy + y^2)
(5h^2)^3 + (3k)^3 = (5h^2 + 3k)((5h^2)^2 - (5h^2)(3k) + (3k)^2)
= (5h^2 + 3k)(25h^4 - 15(h^2)(k) + 9k^2)
This is the second of the given choices.
Answer:
The correct answer is fabric Jimmy's sister needs = × fabric Jimmy needs = × yards of fabric.
Step-by-step explanation:
Jimmy's costume requires ⅞ + ½ + 1 yards of fabric = yards.
His sister's costume requires 3 x (⅞ + ½ + 1 ⅔) the amount of fabric that Jimmy needs = 3× ( ) yards of what Jimmy needs = yards of what Jimmy needs.
The relationship between how much fabric Jimmy needs and how much fabric his sister needs is given by
Fabric Jimmy's sister needs = × fabric Jimmy needs = × yards of fabric.
Multiplication is a way to represent repeated addition. ... Instead, we can write this repeated multiplication using an exponent, which is the number of repeated factors. Exponents are written as a superscript number to the right of the number being multiplied.
