Question

Drag the tiles to the correct boxes to complete the pairs. Match each expression to the correct verbal description. 8 added to the cube of 7x the cube of the sum of 7x and 8 7 times the cube of the sum of x and 8 8 added to the product of 7 and x cubed

Answer 1

1 7(x+8)^3 = 7 times the cube of the sum of x and 8

2 (7x)^3 +8 = 8 added to the cube of 7x

3 (7x+8)^3 = the cube of the sum of 7x and 8

4 7x^3 + 8 = 8 added to the product of 7 and x cubed

Explanation:

I just took this test, its correct. :)

Answer 2

A. (7x)³ + 8 ⇔ 8 added to the product of 7 and x cubed

B. 7x³ + 8 ⇔ 8 added to cube of 7x

C. 7 (x + 8)³ ⇔ 7 times the cube of the sum of x and 8

D. (7x + 8)³ ⇔ the cube of the sum of 7x and 8

Explanation:

1. Let's drag the tiles to the correct boxes to complete the pairs.

A. (7x)³ + 8 ⇔ 8 added to the product of 7 and x cubed

The second tile was already given and solved, however we're copying it.

B. 7x³ + 8 ⇔ 8 added to cube of 7x

C. 7 (x + 8)³ ⇔ 7 times the cube of the sum of x and 8

We use the expression 7 times because number 7 is multiplying the sum inside the parenthesis.

D. (7x + 8)³ ⇔ the cube of the sum of 7x and 8
