Question

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

O 5(4+4)-6
O 5(5(4) - 6) -6
054-6 + 54 - 6
O 5(4) - 6 + 5(4) - 6

Answer 1

Answer:D

Explanation:

5(4)-6+5(4)-6

Answer 2

• 5(4) - 6 + 5(4) - 6

Explanation:

Given

• k(x) = 5x-6

To find

• (k + k)(4)

Solution

• (k + k)(x) = 2*k(x) = 2*(5x - 6)
• (k + k)(4) = 2(5*4 - 6) = 5(4) - 6 + 5(4) - 6

Last option is correct
