Answer:
D. 720cm squared is the answer
To find the value of x, first subtract 3x from both sides to get the variable on one side.
6x-6=3x+10
6x-3x-6=3x-3x+10
3x-6=10
Then add 6 on both sides.
3x-6+6=10+6
3x=16
Divide both sides by 3 to find x.
=
Therefore, x = or 5.3.
2x(x+4)-1(x+4)
2x^2+8x-x-4
2x^2+7x-4
