Answer:
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
Step-by-step 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
