Question

Is 6(-b+8) and 2(-3b+4) equivalent expressions.

Answer 1

no, -6b+48 is not = to -6b+8

Answer 2

They are not equivalent expressions

Explanation:

Let's expand each expression and see if they are the same
6(-b + 8) = 6 x (-b) + 6 x 8 = -6b + 48

2(-3b + 4) = 2 x (-3b) + 2 x 4 = -6b + 8

So while the terms -b are the same, the constants are different

Hence the two expressions are not equivalent
