Answer:

Step-by-step explanation:
Here, we add up two polynomials shown.
The polynomials are:
![[-m^2 + 6]+[-4m^2 +7m + 2]](https://tex.z-dn.net/?f=%5B-m%5E2%20%2B%206%5D%2B%5B-4m%5E2%20%2B7m%20%2B%202%5D)
In order to add up the 2 polynomials shown, we have to see the "like terms" and add them up.
We add up the "
" terms and the constant (number) terms. There is one term with "m", so we leave it like that. Let's add up. Shown below:\
![[-m^2 + 6]+[-4m^2 +7m + 2]\\=-m^2-4m^2+6+2+7m\\=-5m^2+7m+8](https://tex.z-dn.net/?f=%5B-m%5E2%20%2B%206%5D%2B%5B-4m%5E2%20%2B7m%20%2B%202%5D%5C%5C%3D-m%5E2-4m%5E2%2B6%2B2%2B7m%5C%5C%3D-5m%5E2%2B7m%2B8)
This is the sum of the 2 polynomials shown: 
Answer:
15 feet
Step-by-step explanation:
Perimeter = All outside lengths added together
We know that the shape is a square, and squares have 4 sides.
So, divide 60 by 4.
60 / 4 = 15.
The length of one side is 15 feet.
Answer:
The correct answer is 4 window frames.
Step-by-step explanation:
Sue bought 54 feet of lumber for building window frame.
Each window frame requires 13 1/2 feet =
feet of lumber.
Therefore the number of window frames Sue can make with 54 feet of lumbers she bought is given by dividing the total amount of lumber she has by the lumber it takes to make a single window frame.
=
× 2 = 2 × 2 = 4
Thus Sue can make 4 window pane from 54 feet of lumber, each of 13 and a half feet.
