Answer:
p=117.25
Step-by-step explanation:
441/4=110.25
110.25+7=117.25
8 times 4 and 8 divided by 2 i think
1 foot<span> = </span>12<span> inches
</span>864/12=72 T<span>he window is 72 square feet.

The greatest common factor of this can be solved by looking at the individual parts and splitting it up.
First, we have 28 and 7. Well, thats an easy one. 7 goes into 28 4 times so we are now left with 4 and 1.
We can also write the rest of this like this 4(x*x*y) - 1(x*y*y*y*y*y)
Now, what values are in both equations. We have one x and one y that can be taken out of both.
We end up with 7xy(4x-7y^4)
