If the square is the window (I couldn't decipher the grammar/punctuation), the area is 64 feet squared. Since it is a square, the formula to find the area is sxs (side length times side length). 8x8=64, which makes the total area 64 square feet.

1. If you are asked to use elimination to solve for x", what do you need to multiply the bottom equation by to eliminate "y?
hram777 [196]

Answer:

-5

Step-by-step explanation:

There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example

7x + 5y = 19

-5 (2x + y = 19) ---> -10x -5y = 95

this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!
