P=k/(q+4)^2
Replace p=2 and q=2 in the expression to find k.
Once got thr value of k, replace back in thr expression.
Then finally replace q=-2 to obtain a value for p.

See attachment file below. Follow the steps to find p.

Hope it helped!

Hello!

This is simple algebra :)

First, we can write the question as an algebraic equation.

Given that Doug spent 40 more hours than Laura, we can represent Laura as (x) and Doug as (x+40).

"Doug and Laura spent a combined 250 hours." So we can write this as

(x) + (x+40) = 250

Now simplify:

2x + 40 = 250

Solve x by subtracting 40 from both sides of the equation:

2x = 210

Therefore:

x = 210/2

= 105

So Laura (x) spent 105 hours!

Find the sum of the first one hundred positive integers. see fig 6.26
nignag [31]
Here's a pattern to consider:
1+100=101
2+99=101
3+98=101
4+97=101
5+96=101
.....
This question relates to the discovery of Gauss, a mathematician. He found out that if you split 100 from 1-50 and 51-100, you could add them from each end to get a sum of 101. As there are 50 sets of addition, then the total is 50×101=5050
So, the sum of the first 100 positive integers is 5050.

Quick note
We can use a formula to find out the sum of an arithmetic series:
s =  \frac{n(n + 1)}{2}
Where s is the sum of the series and n is the number of terms in the series. It works for the above problem.
