Answer:
feet
Step-by-step explanation:
First, we need to find the height after one year:
2.25 + 1 1/6 =
Now to find the amount in the second year, we can subtract the above amount from 5:
5 - =
So in the second year it grew feet
a
11
3*(3)^2-16
27-16=11
27 and 16
x + y = 43
x - y = 11
You can add up the two equations so the ys are cancelled out.
2x = 54
x = 27
Plug x in to find y.
27 - y = 11
y = 16
