Question

-8(2a-3b)-5(6b)-5(-4a)

Answer 1

-8(2a-3b) -5(6b) -5(-4a)
= -16a+ 24b -30b+ 20a (distributive property)
= (-16a+ 20a)+ (24b -30b)
= 4a -6b

The final answer is 4a-6b~

Answer 2

$-8(2a-3b)-5(6b)-5(-4a) \\ (-8*2a)+(-8*-3b)+(-5*6b)+(-5*-4a) \\ (-16a)+(24b)+(-30b)+(20a) \\ (20a-16a)+(24b-30b) \\ (4a)+(-6b) \\ 4a-6b$
The answer is 4a-6b, which can also be written 2(2a-3b).

Hope this helps!
