It would take exactly 4 years for these trees to be the same height.
Step-by-step explanation:
Given,
Height of Tree A = 9 feet
1 feet = 12 inches
9 feet = 9*12 = 108 inches
Growth rate = 2 inches per year
Let,
y be the number of years.
A(y)= 108 + 2y
Height of Tree B = 8 feet
8 feet = 8*12 = 96 inches
Growth rate = 5 inches per year
B(y)=96+5y
In case of same height;
A(y)=B(y)
![108+2y=96+5y\\108-96=5y-2y\\12=3y\\3y=12](https://tex.z-dn.net/?f=108%2B2y%3D96%2B5y%5C%5C108-96%3D5y-2y%5C%5C12%3D3y%5C%5C3y%3D12)
Dividing both sides by 3
![\frac{3y}{3}=\frac{12}{3}\\y=4](https://tex.z-dn.net/?f=%5Cfrac%7B3y%7D%7B3%7D%3D%5Cfrac%7B12%7D%7B3%7D%5C%5Cy%3D4)
It would take exactly 4 years for these trees to be the same height.

Let "what" and "what" be A and B
Put this in an algebraic equation
A * B = 21
A + B = -22
A must = -21 and B must = -1 , this is because two negatives multiply to make a positive
A + B = -22 , -21 +-1 = -22
Answer:
A:(3x4)+(2x6)=24
B:30-(2x6)
C:(40/((4+1)/3=24
D:(20+1)+(2+1)=24
E:(6x6)-(4x3)=24
