PLEASE HELP, SOLVE THIS PROBLEM AND GIVE ME THE ANSWER!!!

The answer is option B

f(x) = 4x + 8

g(x) = 9x + 7

(fg)(x) = (4x + 8)(9x + 7)

= 36x² + 28x + 72x + 56

= 36x² + 100x + 56

Hope this helps

what is the original number? you forgot to add it.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
