B (x) = 7x + 3 and h (x) = 9x - 1.

Find (b+h) (x)

(b+h) (x) = 16x+2

Since we all know the theory that shows that a (x) + b (x) = (a+b) (x), we can use that in this problem. Simply simplify the problem and divide it into 2 ... b (x) plus h (x). This is simple as we already know the values of these variables so just add both and the sum will be the answer to your problem.
