Answer:The length of the third side 2.5.
Step-by-step explanation:
We already know the length of two side but we don’t know the length of one side so we will represent it by b and we know they three lengths add up to 12b+5.
4b + 3b+15 +b =12b + 5
Solve for b.
8b +15=12b +5
-8b -8b
15+4b +5
-5 -5
4b/4=10/4
B=2.5
So the length of the third side is 2.5
4(2.5) + 3(2.5)+15+2.5=12(2.5)+5
35=35
Answer:
Step-by-step explanation:
The ones digit is an odd number.
4 is an even number.
Can an odd number divide an even number?
This means 644,637 is not divisible by 4.
Solving the quadratic equation we conclude that:
- The maximum height is 45ft.
- The rocket is 18 seconds in the air.
<h3>
How to get the maximum height of the rocket?</h3>
The height of the rocket is defined by the quadratic equation:
The maximum height is what we get in the vertex of the quadratic equation, such that for this quadratic equation, the vertex is at:
So the maximum height is what we get when we evaluate in t = 9:
The maximum height is 45ft.
<h3>How to get the time in the air?</h3>
Now we need to solve the equation for the largest value of t:
Rewriting it, we get:
The maximum solution is what we get when:
0 = 90 - t*5
t = 90/5 = 18
The rocket is 18 seconds in the air.

Since this is going to be an algebraic equation we have to put a variable so ill go with the variable N. Now making an algebraic equation is pretty easy once you have the concept but they will progress over time
N is our variable aka our width
and 3 is our number aka our length
now since it, 2 less than that will be in our equation as 2n
as you know we have to use our variable and our number which is just going to subtract and our answer is 2n-3
when making equation you may use any letter that you would like it does not matter
