Answer:
perimeter of rectangles = 2 ( l + b)
34 = 2 ( x + 2 + 3x - 4 )
34 = 2 ( 4x - 2 )
34 = 8x - 4
38 = 8 x
38/ 8 = x
thus , x = 4.75 inches
So I'm guessing that the x2 is your way of saying 2 is the exponent right? In that case the equation would be 8x^2 + 12x
Well you would have to pull out the gcf which in this case will be 4x after pulling out the gcf you should get 4x(2x + 3)
7 |1 -8 10
X. 7. -7
1 -1 3
A remainder is 3
6x - 2x = 16
4x = 16 |divide both sides by 4
<h3>x = 4</h3>
D. x - 9y + 4 = x + 4 + (-9y)
