45.5 is your answer, you will have to multiple the height times the base ( 5 x 9.1 )
The inverse is (x-2)/3 so the answer is f(x)=0
First you had to add by twenty-two from both sides of equation form.

Then simplify by equation.

Next, you divide by four from both sides of equation form.

Finally, simplify by equation.





Final answer:
