6/x-8=2/x+6 how do i solve this

lutik1710 [3]

6/(x-8)=2/(x+6)
times both sides by (x-8)(x+6)
6(x+6)=2(x-8)
distribute
6x+36=2x-16
minus 2x both sides
4x+36=-16
miinus 36 both sides
4x=-52
divide both sides by 4
x=-13

As a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses

Sergeeva-Olga [200]

Answer:

We have 252 different schedules.

Step-by-step explanation:

We know that as a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses, and one of seven physical education courses.

So from 4 lab science courses we choose 2:

$C_2^4=\frac{4!}{2!(4-2)!}=6$

So from 2 literature courses we choose 1:

$C_1^2=\frac{2!}{1!(2-1)!}=2$

So from 3 math courses we choose 2:

$C_2^3=\frac{3!}{2!(3-2)!}=3\\$

So from 7 physical education courses we choose 1:

$C_1^7=\frac{7!}{1!(7-1)!}=7$

We get: 6 · 2 · 3 · 7 = 252

We have 252 different schedules.

PLEASE HELP! Is the following trinomial factorable why or why not h=-4(4t^(2)-9t+2)

sineoko [7]

Answer:

h = -4(t - 2)(4t - 1)

Step-by-step explanation:

Given trinomial

h= -4(4t² - 9t + 2)

Let's try to factor 4t² - 9t + 2

First find it's zeros:

t = (9 ± √9² - 4*4*2)/(2*4)
t = (9 ± √81 - 32)/8
t = (9 ± 7)/8
t = 2 and t = 1/4

So yes, it is factorable:

4t² - 9t + 2 = 4(t - 2)(t - 1/4)
or
4t² - 9t + 2 = (t - 2)(4t - 1)

The given trinomial factored:

h = -4(t - 2)(4t - 1)
