2x-5 / x+5

Step-by-step explanation:

(2x^2 - 3x - 5) / (x^2 + 6x + 5)

Write -3x as a difference

= (2x^2 +2x - 5x -5) / (x^2+5x+x+5)

Factor out 2x from the expression

= 2x *(x+1) -5 * (x+1) / x*(x+5)+x+5

Factor out x+1 from the expression

= (x+1) * (2x-5) / (x+5)* (x+1)

Reduce the fraction with x+1

= 2x-5 / x+5

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
