What should be subtracted from

pychu [463]

<u>-5a²+13ab</u> should be subtracted.

<h3>Step-by-step explanation:-</h3>

Based on the given conditions, formulate,

$→- {a}^{2} - 4 {a}^{2} + 13ab$

$→-({a}^{2} - 4 {a}^{2}) + 13ab$

Taking the coefficients or numbers, we get,

$→(- 1 - 4) {a}^{2} + 13ab$

$→ - 5 {a}^{2} + 13ab$

It takes the first pipe 9 more hours to fill the pool than the first and the second pipes together and 7 less hours than it woul

Vikki [24]

Let the time taken for the first pipe to fill the pool be x hours
time taken for second pipe to fill the pool is (x+7) hours
time taken for both pipes to fill the pull =(x-9) hours
thus fraction of time taken for both will be written as:
1/(x-9)
thus total fraction for pipe 1 and 2 will be
1/x+1/(x+7)=1/(x-9)
solving for x we get:
x=-3 or x=21
but time is positive, then time taken by first pipe is 21 hours
time taken by both pipes will be 21-9=12 hours
