Simplify x^2 -x-6/4x^3 * 2x^2 +2x/x^2+5x+6 And PLS show work.

Sedbober [7]

To solve this problem you must apply the proccedure shown below:

1. You have the following expression given in the problem above:

$( \frac{x^{2}-x-6}{4x^{3}}) (\frac{x^{2}+2x}{x^{2}+5x+6} )$

2. First, you must factor the polynomials in the numerator and in the denominator and then simplify the expression:

$(\frac{(x-3)(x+2)}{4x^{3}} ) (\frac{2x(x+1)}{(x+3)(x+2)})=\frac{(x-3)(x+1)}{2x^{2}(x+3)(x+2)}$

The answer is: $\frac{(x-3)(x+1)}{2x^{2}(x+3)(x+2)}$

Ten times the sum of half a number and 6 is 8

amm1812

Answer:
The number is -10.4

Explanation:
Assume that the number we are looking for is x.

Now, we want to get 10 times te sum of half the number and 6 and equate this expression to 8. Then we can solve for x

Let's take this step by step:
half the number is 0.5x
the sum of half the number and 6 is 0.5x + 6
10 times the sum of half the number and 6 is 10(0.5x +6)
10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8

Now we can solve for x as follows:
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4

Hope this helps :)

Help a fella out :)))))))

Answer:

5280 ft/1 mi, 1848 ft

Step-by-step explanation:

Whatever unit is given on the top (miles), you will write it on the bottom of the second fraction. Since we are solving for length in feet, we know that the numerator will be in feet. The only answer choice that has this option is 5280 ft/ 1 mi. You can check this math by taking 0.35 of 5280 feet, or 1 mile = 1848 ft.

$\frac{0.35 mi}{1} *\frac{?ft}{?mi}$

$\frac{0.35 mi}{1} *\frac{5280 ft}{1mi}$ (miles cancels out, left with feet)

$\frac{1848ft}{1}$

1848 feet

I hope this helps!
