If a pine tree grows 4 inches per year, how long will it take for the tree to reach a height of 13 feet?

39 yr

Step-by-step explanation:

Convert "4 inches per year" to "feet per year:"

4 inches       1 ft

* = (1/3) ft/yr

  1 year        12 in

Now we know the growth rate.  The time required to reach a certain height is

3 yr

* 13 ft = 39 yr

 1 ft

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

the answer is 2/54
