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

 the correct option is

(D)

Step-by-step explanation:  Given that the function k(x) is written as :

We are to select the expression that is equivalent to (k + k)(4).

We know that

if f(x) and g(x) are any two functions, then

Therefore, we get

Thus, we get

Option (D) is CORRECT.

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept
