Simplify this expression

kompoz [17]

The first step for solving this problem is to know that in order to divide by a fraction,, we must multiply by the reciprocal of that fraction. This will look like the following:
$\frac{x+2}{ x^{2} -6x-16}$ × 9x
Write -6x as a difference.
$\frac{x+2}{ x^{2} +2x-8x-16}$ × 9x
Factor out x from x² + 2x.
$\frac{x+2}{ x X (x+2)-8x-16}$ × 9x
Factor out -8 from -8(x + 2).
$\frac{x+2}{ x X (x+2)-8(x+2)}$ × 9x
Factor out x + 2 from the denominator (bottom) of the expression.
$\frac{x+2}{(x+2)X(x-8)}$ × 9x
Reduce the fraction with x + 2
$\frac{1}{x-8}$ × 9x
Finally,, calculate the product to find your final answer.
$\frac{9x}{x-8}$
This means that the correct answer to your question is going to be option B.
Let me know if you have any further questions.

A square is removed from the right hand corner of a square board. What is the area of the remaining board in square feet?

Mama L [17]

<h2>Answer:</h2>

The area of the remaining board in square feet is:

108 square feet.

<h2>Step-by-step explanation:</h2>

The remaining area of board=

Area of the whole board-Area of square which is removed.

i.e.

Area of remaining board= Area of square of side length 12 feet-Area of square with side length 6 feet.

We know that the area of square with side length s units is given by: s² square units

Hence, we get:

Area of remaining board= (12)²-(6)²

i.e.

Area of remaining board= 144-36

i.e.

Area of remaining board= 108 square feet.
