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)
Dividing both sides by 3
It would take exactly 4 years for these trees to be the same height.

Answer:
-x^2-2x-3
Step-by-step explanation:
- Question 1: Just substitute in the values of f(x) and g(x) and simplify!
- f(x) - g(x) = 4x^2-5x+3-(5x^2-3x+6)
- f(x)-g(x) = 4x^2-5x+3-5x^2+3x-6
- f(x)-g(x) = -x^2-2x-3
Tell me if this helps, and if you still need number 2 or if you can do it by yourself! (Hint: substituting also plays a role in question number 2.)
Hope this helps!!
4 1/4 = 17/4
17/4 -3/4 = 14/4 = 3 2/4 = 3 1/2
This expression would be written as x/-2
When we write expressions of sentences like this, we need to separate out the different terms.
Quotient means to divide.
A number is written as x when we don't have a variable.
-2 is -2.
x/-2
Answer:
180 millimeters.
Step-by-step explanation:
To find the height of the replica, a ratio can be set up:
Cross multiply:
Divide both sides by '275:
x≈0.18 meters
Convert 'meters' to 'millimeters' by multiplying by a thousand:
0.18 × 1000 = 180 millimeters.
