Question

Which two expressions are equivalent?

(F was wrong) H 7(x − 3) and 7x − 7 • 3
g 7(x − 3) and 7x − 4 j 7(x − 3) and 7x + 7 • 3

Answer 1

The correct answer is:

Option H: 7(x − 3) and 7x − 7 • 3

Explanation:

Equivalent expressions are those expressions that simplify to the same expression i.e. the result of both expressions is the same. There is no change of sign or variable or any quantity.

Option H:

The two expressions are:

7(x − 3) and 7x − 7 • 3

`7(x-3) = 7x - 21\\7x - 7.3 = 7x-21`

It can clearly be seen that both the expressions result in same expression

Hence,

The correct answer is:

Option H: 7(x − 3) and 7x − 7 • 3
