(f∘g)(x) is equivalent to f(g(x)). We solve this problem just as we solve f(x). But since it asks us to find out f(g(x)), in f(x), each time we encounter x, we replace it with g(x).
In the above problem, f(x)=x+3.
Therefore, f(g(x))=g(x)+3.
⇒(f∘g)(x)=2x−7+3
⇒(f∘g)(x)=2x−4
Basically, write the g(x) equation where you see the x in the f(x) equation.
f∘g(x)=(g(x))+3 Replace g(x) with the equation
f∘g(x)=(2x−7)+3
f∘g(x)=2x−7+3 we just took away the parentheses
f∘g(x)=2x−4 Because the −7+3=4
This is it
g∘f(x) would be the other way around
g∘f(x)=2(x+3)−7
now you have to multiply what is inside parentheses by 2 because thats whats directly in front of them.
g∘f(x)=2x+6−7
Next, +6−7=−1
g∘f(x)=2x−1
Its a lts easier than you think!
Hope this helped

Answer:
9ft
Step-by-step explanation:
The area is 135ft and the formula for area is length x width.
on the image it shows the height is 5yds and we want feet since that's that the area is in. a yard = 3 feet so its 3 x 5 = 15.
since the formula to find area is multiplication, use division to find a number in the equation. so
135 divided by 15 = 9.
The length of the base is 9ft.
Hey! I'll provide the steps required.
First, solved the proportion by cross multiplication.
Then use the commutative property to reorder the terms as well as multiply the numbers.
90x = 9720
Finally, divide it by 90.
x = 108
