Joe makes a poster from a photo. He cuts 2 inches from the top and bottom of the photo then enlarges the photo to 3 times the original size. The expression 3(h−4) models the poster height, where h is the original photo height. Which is the poster height when the original photo height h is 1112 inches?

3,324 inches

Step-by-step explanation:

Hi, to answer this question we have to substitute h=1112 in the expression given, and then, solve it:

3(h−4)

Substituting:

3 (1112-4)

Solving:

3 (1108)

3,324  

The poster height when the original photo height h is 1112 inches is 3,324 inches.

Feel free to ask for more if needed or if you did not understand something.

Step-by-step explanation:

h(-3) = 4 + 3 = 7

g(7)= 7 + 1/7 - 7 = 1/7
