Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cubes, a3 + b3. his teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y. which product should tomas choose? (2x + y)(2x2 + 2xy – y2) (2x + y)(4x2 + 2xy – y2) (2x + y)(4x2 – 2xy + y2) (2x + y)(2x2 – 2xy + y2)

Step-by-step explanation:

The expression for sum of cube is given as:

When we put a=2x and b=y into this formula, we obtain:

We simplify to get:

Therefore the correct  choice is

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
