Goodluck on your assignment...

Answer:

X = 6

Step-by-step explanation:

Cross Multiplication

We can go about this 1 of 2 ways we can either cross multiply or divide across the numerators and denominators. Let's cross multiply. We would 4*9 = 6x. Which would simplify down to 36 = 6x. We would then divide the 6 on each sides of the equation to get 6 = X.

Dividing Across

The other way we can go about it is by seeing what 4 had to be multiplied by to get to 6. We do this by dividing 6 by for which gets us 3/2 or 1.5. Now that we know this we would then divide 9 by 3/2 or 1.5 to get the answer of 6.

We know that the area of a parallelogram is the base * the height of it, so if we divide both sides by the height, then area/height=base. Therefore, we must divide the area by the height. To divide using polynomials, we first set it up similar to a regular long division problem:

        ______________________

2x+3 | 2x²+13x+15

Next, we take the first component of the numerator (2x² in this case) and divide it by the first component of the denominator (2x) to get x. That will form the start of our answer, and at the bottom, we will subtract our numerator by the denominator (2x+3) multiplied by the start of our answer (x). Therefore, we have

          _x_____________________

2x+3 | 2x²+13x+15

        -(2x²+3x)

        _______________

                10x+15

We then repeat the process until we finish, and whatever's left at the top is our answer. If there's something left, that's our remainder.

_x+5_____________________

2x+3 | 2x²+13x+15

        -(2x²+3x)

        _______________

                10x+15

             - (10x+15)

     _________________

0

Therefore, our base has a length of x+5.
