Question

If k(x) = 5x – 6, which expression is equivalent to (k + k)(4)?
5(5(4) – 6) – 6
54 – 6 + 54 – 6
5(4) – 6 + 5(4) – 6

Answer 1

Do you know what k is?

Answer 2

@PsychoTink i havent got a clue, lol

Answer 3

Because of the "k(x)" You know that k is the equation overall, with x as the unknown you are solving for.

So what it looks to me like they are asking you to solve is k plus k where you plug 4 in for x.

Answer 4

yeah,

Answer 5

Do you still need help or does that make sense?

Answer 6
