drag the tiles to the correct boxes to complete the pairs match each expression to the correct verb description
2 answers:
The verbal description are matched with the mathematical expressions as follows:
The cube of the sum of 7x and 8 ⇒ (7x + 8)³
8 added to 7 and x cubed ⇒ 7x³ + 8
8 added to the cube of 7x ⇒ (7x)³ + 8
7 times the cube of the sum of x and 8 ⇒ 7(x + 8)³
Answers and justitication:
1) (7x)^3 + 8→ 8 added to the cube of 7x
becasue the cube of 7x is (7x)^3 and then 8 is added to it.
2) (7x + 8)^3 → the cube of the sum of 7x + 8
because first you add 8 to 7x and then the result is cubed.
3) 7x^3 + 8 → 8 added to 7 and x cubed.
4) 7(x+8)^3 → 7 times the cube of the sum of x and 8.
because first 8 is added to 8, then the result is cubed, and finally the result is multiplied by 7.
