Simplify completely (6x² - 54x + 84 / 8x² -40 x +48) ÷ (x² + x - 56 / 2x² + 12x -32)
VladimirAG [237]

Answer:

The answer to your question is     \frac{3(x - 2)}{2(x - 3)} or \frac{3x - 6}{2x - 6}

Step-by-step explanation:

Expression \frac{6x^{2}- 54x + 84}{8x^{2} - 40x + 48} /  \frac{ x^{2} + x - 56}{2x^{2} + 12x - 32}

Process

1.- Change the division to a multiplication

                   \frac{6x^{2}- 54x + 84}{8x^{2} - 40x + 48} x \frac{2x^{2}+ 12x - 32}{x^{2} + x - 56}

2.- Factor

                   \frac{6(x^{2}- 9x - 14)}{8(x^{2} - 5x + 6)} x \frac{2(x^{2}+ 6x - 16)}{(x^{2} + x -56)}

                   \frac{6(x + 8)(x - 2)}{8(x - 3)(x - 2)} x \frac{2(x + 8)(x - 2)}{(x + 8)(x - 7)}

3.- Simplify (cancel the terms that are repeated in both numerator and denominator)

                  \frac{2(6)(x - 2)}{8(x - 3)}

                  \frac{3(x - 2)}{2(x - 3)} or \frac{3x - 6}{2x - 6}

I NEED HELP ASAP<br> Answer these two questions I am confused. Number 17 and 18.
devlian [24]

Answer:

Step-by-step explanation:

Question 17

y-y1 = m (x-x1 )

so basically you plug in the (x,y) to y1 and x1 place

Remeber always times it by -1

so answer would be

y-2 = -1/3 (x+4)

Question 18

Pretend its 3x+2y =8

you need to find x or y first im going to find y first

so

- 2y = -3x +8

divide by 2 to isolate y

y = -3/2x - 4

plug it back into the equation

3x + 2(-3/2x) - 4

the x will cancel

so y= -4

Then

plug in the -4 in place of y

SO the Answer is YES because y is horizontal there is -4 = there will be (-3, -4)!

A race is 3 miles long. There are water stations every 3/4 mile along the route. How many water stations are along the route?
Vilka [71]
There will be 4 water stations.

Why?

3/4 = .75 as a decimal

Personally, I believe that it’s easier to use decimals, I can explain the way in fractions in the comments if you’d like, just ask.

Anyway, .75 • 4= 3

or 3 / .75 = 4 (division is easier with bigger numbers)

so, there will be 4 water stations, given that the one race is 3 miles long.

If this explanation seems unclear, I’d be happy to explain. Feel free to ask in the comments!! I’m happy to help.

Hope this helps!
