N = 4

12 x 6 = n x 18
72 = n x 18
n x 18 = 72
n x 18/18 = 72/18
18 and 18 cancel each other out
72 divides by 18 is 4
n = 4

Please help ASAP! <br> Use (f/g)x<br> f(x)=6x^2+36<br> g(x)=6x^2+34x-12<br> Show your work please!

Answer:

$\frac{3}{3x-1}$

Step-by-step explanation:

$\frac{f(x)}{g(x)}\\\frac{6x^2+36}{6x^2+34x-12}\\\frac{6(x^2+6)}{2(3x^2+17x-6)}$ Factor out a 6 from the numerator and 2 from the denominator

$\frac{3(x^2+6)}{3x^2+17x-6}$ 2 in the denominator divides the 6 in the numerator

$\frac{3(x+6)}{(3x-1)(x+6)}$ factor the denominator, let me know if you need help with this

$\frac{3}{3x-1}$ the (x+6)s cancel

OLga [1]

Answer:

3.54 and 1.04

Step-by-step explanation:

Given:

Two towns are 1,100 miles apart.

A group of hikers Starts from each town and walks down the trail toward each other..

They meet after a total hiking time of 240 hours.

If one group travels 2 1/2 mile per hour slower than the other group.

<u>Question asked:</u>

Find the rate of each group.

<u>Solution:</u>

Let speed of faster hiker = $x\ mph$

Speed of slower hiker = $x-\frac{5}{2}\ mph$

<u>As we know:</u>

<u /> $Distance=speed\times time$

Total distance between two town = Total combined speed of both hikers $\times$ Total combined time taken

$1100=(x+x-\frac{5}{2} )\times240\\ \\ Dividing\ both\ sides\ by\ 240\\ \\ 4.58=(x+x-\frac{5}{2} )\\ \\ 4.58=2x-\frac{5}{2} \\ \\Adding\ both\ sides\ by\ \frac{5}{2} \\ \\ 4.58+ \frac{5}{2}=2x- \frac{5}{2}+ \frac{5}{2}\\ \\ \frac{2\times4.58+5}{2} =2x\\ \\ \frac{14.16}{2} =2x\\ \\ By \ cross\ multiplication\\ \\ 2\times2x=14.16\\ \\ 4x=14.16$

$By\ dividing\ both\ sides\ by \ 4\\ \\ x=3.54\ miles\ per\ hour$

Speed of faster hiker = $x\ mph$ = 3.54 miles per hour.

Speed of slower hiker = $x-\frac{5}{2}\ mph$ =

$3.54-\frac{5}{2} =3.54-2.5=1.04\ miles\ per\ hour$

Therefore, speed of faster hiker is 3.54 miles per hour and speed of slower hiker is 1.04 miles per hour.
