In simplest form it is 25 over 9
Answer:45,311
45,301+10=45,311
I hope this is good enough:
Complete the square
isolate x terms
y=(x^2-14x)+53
take 1/2 of -14 and square it ((-7)^2=49
add plus and minus of that inside the parntehasees
y=(x^2-14x+49-49)+53
factor perfect suqrae
y=((x-7)^2-49)+53
get rid of parnthasees
y=(x-7)^2-49+53
y=(x-7)^2+4
C isi answer
To answer this, you just go around multiplying the terms from the first set by everything in the second set. (For example, multiply 2x^2 by x^2, next by -2x, and finally by 5)
2 hoses together:
15 mins = 1 pond
1 min = 1/15 pond
1st hose:
24 mins = 1 pond
1 min = 1/24 pond
2nd hose:
1 min = 1/15 - 1/24 = 1/40 pond
So 1/40 of the pond = 1 min
40/40 of the pond = 1 x 40 mins
1 whole pond = 40 mins
---------------------------------------------------------------------------------------------------
Answer: it will take 40 mins for the 2nd hose to fill up the pond alone.
