Question

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

Answer 1

5(4+4)-6

Answer 2

if k(x) = 3x + 2
(k + k)(4) is = ?
first let us try to solve when x =4
k(4) = 3(4) + 2 = 14

for intellectual exercise, what would it mean to say 1/k (x) then?
it means 1/(3x +2)

expanding from this knowledge-
(k+k)(x) means k(x) + k(x), which then
(3x + 2) + (3x + 2)
(k + k)(4) would be processed as
(3(4) + 2)+(3(4) + 2)
12 + 2 + 12 + 2 = 28

go ahead and try to solve your problem
