how u dont know this stuff shhhhh on yo ahh boi
The answer is 3x.
Factor out 3x and u get 3x(x-3).
180x feet^3
this is the answer because volume is lwh so 15 x 12 x x is 180x the labeled is 180x ft.^3
You have to make an equation that i forgot what was called but you just take
x+y=10 and multiply it by -2 so the y’s can cancel out
so you’ll end up with:
-2x-2y= -20
(+) x+2y=14
you’ll get : x = -6
then you plug in -6 for x, solve for y and your coordinates will be
(-6 , 10)
