Question

Which expressions are equivalent to − 90 − 60 w?

Answer 1

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Using distributive property:

A : -30(3+2w) = -90 - 60w : equivalent to -90 - 60w

B : (-9-6w) ⋅ 10 = -90 - 60w : equivalent to -90 - 60w

C : -3(30 - 20w) = -90 + 60w : NOT equivalent to -90 - 60w

D : (6 + 4w)×15 = 90 + 60w : NOT equivalent to -90 - 60w

E : −20(4.5 + 3w) = - 90 - 60w : equivalent to -90 - 60w

SO THAT MEANS

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)
