Well think about it this way -9 times what equals 252 you already know x is going to be a negative number because the outcome is positive so try doing the problem backwards 252/-9=-28 so x=-28
Well it will be a simple as grid algebra
3(2+12)+12x5
16 length height bc it’s a triangle so the triangle will be 17 feet tall and long
First half is negative and second is positive
