Please help ASAP 50 points :(((
Katyanochek1 [597]

Answer:

(f o g) (x) = 36x² + 3

(g o f) (x)  = 6x² + 18

Step-by-step explanation:

f(x) is x² + 3  

g(x) is 6x

(f o g) (x) means for all xs in f replace it with g(x) or 6x

(f o g) (x) = (6x)² + 3  - see 6x is in place of x and 6x is g(x)

(f o g) (x) = 36x² + 3

(g o f) (x)  = 6(x² + 3)  

(g o f) (x)  = 6x² + 18

Andre45 [30]

Answer:

So since the scale is 12 inches:5 feet, we have to divide 412 inches by 12 inches because 412 inches is the total length drawn on the scale drawing.

412/12 = 34.3

Then since each 12 inches equals 5 feet and we have 34.3 12x inches. We are just going to multiply 34.3 by 5.

34.3*5 = 171 and 2/3 feet is your actual length of the bus
