The initial height of the tree = 7 ft
Each year the tree grows 6 in. 6 in = 6 / 12 = 0.5 ft
So the tree grows 0.5 ft every year.
After x years, the tree would have grown extra = 0.5*x =0.5x
So the height of the tree would be = Initial height + extra height grown
= 7 + 0.5x
h = 7 + 0.5x
Model is h = 7 + 0.5x,
where h = height of the tree in feet after x years.
Hope this explains it.
An expression when dealing with math does not have an equal sign. So, technically 12m + 12n is already an expression.
It can be simplified to
12(m + n) if that helps any. Good luck!
Lines on a railroad track are parallel lines.
Parallel lines are two or more lines that are in the same plane (flat space) and are always equal distances apart from each other at all points on the line.
Answer:
4/5 x^3
Step-by-step explanation:
20x/25x^-2
Divide the coefficients
20/25 = 4/5
When dividing exponents we subtract
x/ x^-2 = x^ (1- -2) = x^3
Putting back together
4/5 x^3
