-6x+12 because you are multiplying -3 and 2x and -3 and -4
I think you take 5374.60.7 subtract 56.89 and then divide it by 22.70, that’s what I did and I got 234
C squared = a squared+ b squared (formula)
so therefore
(c longest side) (this is your x)
(a and b shorter sides).
C squared = 5 squared + 3 squared
C squared = 25 + 9
C squared = 31
Then you find the square root of c (which is just getting rid of the squared sign) and the square root of 31 And that is your answer
Hope this helps!!
It’s -33 my work is in the picture
Well to find the area you do Length * Width * Height, so it should be 150
