The function f(x) = x + 3 represents the length of a rectangle. the function g(x) = 12x − 5 represents the width of the rectangle. use (f • g)(3) to determine the area of the rectangle. 186 37 31 6

186-I just took the test and the first one is right.

Step-by-step explanation:

Replace x with 3 in both equations,then multiply the answers:

f(x)=x+3

f(3)=3+3

f(3)=6

g(x)=12x-5

g(3)=12(3)-5

g(3)=36-5

g(3)=31

6*31=186

Hope this helps :)

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
