Answer 1

3

Explanation:

Hi ! Our task is to simplify the expression:

`\sf{\cfrac{5^2-4}{5+2}}`

Do the exponents first:

`\sf{\cfrac{5*5-4}{5+2}}`

`\sf{\cfrac{25-4}{7}}`

`\sf{\cfrac{21}{7}}`

`\sf{3}`

Therefore, 3 is the answer to this problem.

Answer 2

Answer: 21/7 or 3 wholes

Explanation:

5^2 = 25

25-4 = 21

5+2 = 7

so

21/7, made into wholes is 3 since 21 divided by 7 is 3.
