Match each expression to the correct verbal description.

Answer 1

Hello!

The answers are:

First box: 7 times the cube of the sum of x and 8

Second box: 8 added to the cube of 7x.

Third box: 8 added to 7 and x cubed.

Fourth box: the cube of the sum of 7x and 8.

Why?

We are given the expression and we need to macth to the correct verbal description, so we have:

First box:

`7(x+8)x^(3)`

It's 7 times the cube of the sum of x and 8

Second box:

`(7x)^(3)+8`

We have that "7x" is cubed and then, added to 8, so, it's 8 added to the cube of 7x.

Third box:

`7x^(3)+8`

We have "7" times "x" cubed and added to 8, so it's 8 added to 7 and x cubed.

Fourth box:

`(7x+8)x^(3)`

We have "7x" added to 8, and the expression is cubed, so, it's the cube of the sum of 7x and 8.

Have a nice day!
