The area of a triangle whose height is 1 more than 6 times its base is 13 square feet. if the base of the triangle is x feet, which equation models this situation? a. 612+1-12 = 0 b. 612+1-13 = 0 c. 652+1-26=0 d. 3632+63-26 = 0

- The equation is 6x^2 +x -26 =0  so i'm kinda in between if it's 'A' or 'C' but since 'C' seems the closest then just go for it and pick that answer, but who knows maybe i'm wrong.

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.
