The answers are 3 and -13
You need to plug 3 and -5 into x
By doing this, you get :
12 - 3^2 and
12 - (-5)^2
those expressions equal
12 - 9
12 - 25
So you get
3
-13

Answer:
The fraction of wood used for horizontal support is
.
Step-by-step explanation:
Assume that the total piece of wood is of length 1.
It is provided that Talia used
of the piece of wood for the base of he project.
She use
of the piece of wood for the for the vertical support.
The remaining wood she used for horizontal support.
The amount of wood used for horizontal support can be computed by the subtracting the amount of wood used for base of the project and vertical support form 1.
Compute the amount of wood used for horizontal support as follows:

Thus, the fraction of wood used for horizontal support is
.
1 ? I checked on the calculator and it said 1
You can't find the exact value of y, but you can find y in terms of x!
Adding 3y and subtracting 8 from both sides, we have:
2x-3y+3y-8=8+3y-8
2x-8=3y
Dividing by 3, we see that y=(2x-8)/3. This is the simplest form we can find for y.
