Answer:

1 would complete the square

Step-by-step explanation:

In order to solve this you have to remember the formlua for the perfect quadratic trinomial:

a^2 + 2 ab +b^2=0

IN the example you have A^2 and 2ab, since A=1, then the 2x will resulto from the multiplication of b and a multiplied by 2, so we just have to divide 2x by 2x to get b:

\frac{2x}{2x}=1

So we get that b is 1.

A pump fills a pool at the rate of 20 cubic meters in an hour. If each cubic meter of water costs $10, how many minutes will the
fomenos

The first thing any good mathematician does is convert the measurements to the same unit as what the question is asking. In this problem, it states that the pool fills at a rate of 20 cubic meters per hour. Just keep in mind that an hour is 60 minutes.

The next step is to see how many cubic meters will cost $300. This can be done by dividing 300 by 10. This gets you 30 cubic meters of water.

You already know that 60 minutes is 20 cubic meters of water. That leaves the remaining 10 cubic meters of water. By dividing the rate given, you get that 30 minutes is 10 cubic meters of water. Add the 60 and 30 together to get 90 minutes.

It will take 90 minutes for the pump to use $300.
