Question

Someone please help! I'm confused with c and d.

Answer 1

Answer:

The phrase which matches the algebraic expression  3(x + 7) + 10 is:

Three times the sum of x and seven plus ten

Step-by-step explanation:

We have to find the phrase which matches the algebraic expression:

3(x + 7) + 10

3(x+7) means three times the sum of x and seven

So,

3(x+7)+10 means three times the sum of x and seven plus ten

Hence,

The phrase which matches the algebraic expression  3(x + 7) + 10 is:

Three times the sum of x and seven plus ten

Answer 2

It would be 3 times the sum of x and seven plus 10. This is because first you would would add 7+x (7x) and multiply it by 3. And then add on 10.
