Which expressions are equivalent to -90 - 60w
a : -30(3+2w)
b : (-9-6w) ⋅ 10
c : -3(30 - 20w)
d : (6 + 4w)×15
e : −20(4.5 + 3w)

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Step-by-step explanation:

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

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)
