For the given functions f and g, complete parts (a)-(h). For parts (a)-(d), also find the domain. f(x) = 5x + 3; g(x) = 3x - 7
(a) Find (f +g)(x).
(f + g)(x)=(Simplify your answer.)

I really don’t know how to do this like I really do need help if somebody could just please explain it in detail

Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x). To find the answers, all I have to do is apply the operations (plus, minus, times

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
