I didn't understand this to be honest I thought I had to find what jm and lm were together and then subtract from the whole tota
prisoha [69]

Answer:

The correct answer is 3x-2

Step-by-step explanation:

It gives you the expression for JM and LM, and it asks for JL. Therefore, if you take away LM from JM, you are left with JL. You must subtract 2x-6 from 5x-8.

∴5x-8-(2x-6)

Do not forget to distribute the negative since you are subtracting, so instead of subtracting 6 from 8, you will be adding 6 to 8 because two negatives make a positive.

Marcus is building a fence around his rectangular backyard. The length of his backyard is 75 3/4 ft, and the width is 81 1/4 ft.
Allisa [31]

Answer:

Step-by-step explanation:

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished  = 4,923.75ft²

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.
