please help, i need help with thee two problems and i swear if you are one of those people that just put links as scams, pls dont:D

ugh i hate those ppl with the links

anyways

1) 16t^2 = 144

4t = 12

t = 3

2) x^2 + 10x + 25 = 9

x^2 + 10x + 16 = 0

(x+8)(x+2) = 0

x = -8 or -2

Hope this helps :)

ANSWER TO 1 is t = 3

ANSWER TO 2 is x = -2

Step-by-step explanation:

2) x^2 + 10x + 25 = 9

x^2 + 10x + 16 = 0

(x+8)(x+2) = 0

x=-2

1) 16t^2 = 144

4t = 12

t=3

step-by-step explanation:

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.
