Answer:
3528 inches
Step-by-step explanation:
If you take the length of the bookcase (84 inches) and divide it by two you get 42 inches. 42 inches is half of 84 inches. To find the area of the section of the wall the bookcase will cover, you have to take 84 and multiply it by 42. If you do this, you get the answer, which is 3528 inches. Apologies if I'm wrong, but I'm sure that I am 99.99% right.
There is not a gcf because one is odd and the other even
There is two answers D and B
X+4y+x+y= 4x+y=180
simplify by adding like terms
2x+5y= 4x+y=180
Subtract y from each side
2x+4y=4x=180
Subtract 2x from each side
4y=2x=180
y=180/4=45
x=180/2=90
9 is the answer negatives cancel out creating positve
