Agardener is planting two types of trees: type a is 5 feet tall and grows at a rate of 18 inches per year. type b is 8 feet tall and grows at a rate of 14 inches per year. algebraically determine exactly how many years it will take for these trees to be the same height.

9 years

Step-by-step explanation:

The first thing that you need to do is convert 5 feet and 8 feet into inches.

5 x 12 = 60

8 x 12 = 96

The equation to solve this problem when the number of years equals x is:

60 + 18x = 96 + 14x

First, subtract 60 from each side:

18x = 36 + 14x

Next, subract 14x from each side:

4x = 36

Divide both sides by 4:

X = 9 years

for the first one,

I would prolly distribute the number on the outside of the parenthesis into the first pair of parenthesis but keep the parenthesis there, so for #17 it would turn out to be (2x-2)(x+2),

and then use foil (first outer inner last). so then #17 is 2x^2 + 4x - 2x - 4

and then you'd combine like terms to get the 2x^2 + 2x -4

Step-by-step explanation:

hope this helped a little bit :))
