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

Expression equivalent to (k + k)(4) is 28.

Step-by-step explanation:

Given:

k(x) = 5x - 6

We need to find expression equivalent to (k + k)(4)

First we find,

(k + k)(x) = k(x) + k(x)

             = ( 5x - 6 ) + ( 5x - 6 )

             = 5x - 6 + 5x - 6

             = 5x + 5x - 6 - 6

             = 10x - 12

Now, (k + k)(4) = 10(4) - 12 = 40 - 12 = 28

Therefore, Expression equivalent to (k + k)(4) is 28.

okay wait before i answer, is this for your points on a graph?
