Answer 1

Answer:

[a] Two times the sum of x and seven plus ten    

Answer 2

Option A

ANSWER:

Two times the sum of x and seven plus ten first matches 2(x + 7) + 10

SOLUTION:

Given, algebraic expression is 2(x + 7) + 10.

We have to find the sentence phrase for given algebraic expression.

Now, as we can see,  two terms 2(x + 7) and 10 are added.

And, x + 7 is multiplied with 2.

So two times the x + 7 is added to ten.

Now, we can phrase x + 7 as sum of x and 7

So, two times the sum of x and seven is added to ten.

It can also be written as two times the sum of x and seven plus ten.

Hence, first option A is correct.
