A. x = -6
6-x-x = 18
6-2x =18
-2x = 12
x = -6
You must follow the steps below:
1. First, you should apply the dstributive property:
=(x²-<span>8x+15/3x)(8x/x-3)
=(8</span>x³-64x²+120x)/3x(x-3)
2. As you can see, the common factor in the numerator is: "8x". So, you have:
=8x(x²-8x+15)/3x(x-3)
3. Then, when you simplify, you obtain:
=8(x²-8x+15)/3(x-3)
Therefore, the solution is: 8(x²-8x+15)/3(x-3)
Answer: 3/16
3/4 divide 4 is:
3/4 times 1/4=
3/16
6 x 9 = 54
He has a total of 54 pages to grade.
