Answer:

205 litres

Step-by-step explanation:

Given:

Volume of water is given as:

V=100+20m (in litres)

<em>m</em> is the time in minutes spent filling water in Eduardo's pool.

To find:

Volume of water in the pool after the water is filled for 5\frac{1}{4} minutes.

Solution:

Here, volume of water in the Pool (in litres) is given by the equation:

V=100+20m ....... (1)

Where m is the time for which Eduardo fills the pool.

Here, we are also given that

m = 5\frac{1}{4} minutes = \frac{5\times4+1 }{4}=\frac{20+1}{4}=\frac{21}{4} minutes

And we have to find the value of V after \frac{21}{4} minutes.

Let us put the value of m as \frac{21}{4} minutes in the equation (1) to find the value of V.

V=100+20m\\\Rightarrow V = 100 + 20 \times \frac{21}{4}\\\Rightarrow V = 100+105\\\Rightarrow \bold{V = 205\ litres}

So, the volume of water in the pool after \frac{21}{4} minutes is <em>205 litres.</em>

I am confused on how to do this
babymother [125]
So, u would start by expanding the bracket and ignoring the 2 at the moment.
(x+9)(x+9)= x^2-18x+81(using the foil method!

Then u would put 2 at the front to get:
2(x^2+18x+81)
= 2x^2+36x+162
