Question

which expression is equivalent to 28 plus 35 ? A) 28 (1 plus 7) B) 7( 4 plus 5) C) 7( 4 plus 7) D) 4) ( 7 plus 9)

Answer 1

B. 28/4=7 and 35/5=7.

Answer 2

Hey there!

For this one, we need to use the distributive property which states that:

a(b+c) = ab + ac

If we look at A, it says:

28(1+7) which would get us 28(1) + 28(7) which does not equal 28+45

For B, we have:

7(4 + 5), which equals 7(4) + 7(5) = 28 + 35.

Therefore, B is your answer.

Hope this helps!
