bogdanovich [222]

Answer:

$\left(x-y\right)^2\left(1-x+y\right)$

Step-by-step explanation:

You factor out the common term first.

You should get the equation below.

$\left(x-y\right)^2\left(1-\left(x-y\right)\right)$

then you get rid of the negative inside $\left(1-\left(x-y\right)\right)$

and will be simplified to this.

$\left(x-y\right)^2\left(1-x+y\right)$

a leaky faucet is losing water and is filling a 5-gallon bucket every 20 hours. At that rate, how many gallons of water will the

Arisa [49]

You can either scale down so you can get to 48 hours or just multiply from 20 to 48 and I'll explain both ways.
Scaling down:
You can find how many hours it takes to get to 1 gallon in the bucket by dividing
20÷5=4; It takes 4 hours to fill it up to one gallon.
You can now divide 48 by 4 to see how many gallons it'll take up to 48 hours.
48÷4=12
Quicker:
Divide 48 by 20;
48÷20=2.4
Now multiply since it filled it up to 5 gallons.
2.4×5=12
It'll fill 12 gallons in 48 hours.

The LCD of 3 and 4 is 12. To make 4 into 12, we multiply it by three, so 3 would also have to be multiply by 3, turning 3/4 into 9/12.

The same thing applies to 1/3, only it needs to be multiplied by 4. So it would become 4/12

9/12 - 4/12 = 5/12
