First, subtract the height he will grow to to the height he is now.
132 - 90 = 42
Now divide this from 3.5.
42 / 3.5 = 12
So it will take 12 months for him to grow to a height of 132 cm.

Answer:
-2.1
Step-by-step explanation:
We have an equation and the question is asking us to look for x.
To solve, we must isolate x and get it on its own.
2.5(x + 4) = 4.75
Distribute the 2.5 to get rid of the parenthesis :
(2.5(x) + 4(2.5)) = 4.75
2.5x + 10 = 4.75
Subtract ten from both sides :
2.5x = -5.25
Divide 2.5 by both sides to get x alone :
x = -2.1
