Step 1
Given;
![w=\frac{p-4i}{2-3i}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7Bp-4i%7D%7B2-3i%7D)
Required; To express w in the form of a+bi.
Step 2
Express w in the form of a+bi
Multiply the numerator and the denominator by the binomial conjugate of (2-3i)
The binomial conjugate of (2-3i) = (2+3i)
![w=(\frac{p-4i}{2-3i})\times(\frac{2+3i}{2+3i})=\frac{2p+3pi-8i-12i^2}{4+6i-6i-9i^2}](https://tex.z-dn.net/?f=w%3D%28%5Cfrac%7Bp-4i%7D%7B2-3i%7D%29%5Ctimes%28%5Cfrac%7B2%2B3i%7D%7B2%2B3i%7D%29%3D%5Cfrac%7B2p%2B3pi-8i-12i%5E2%7D%7B4%2B6i-6i-9i%5E2%7D)

where;
I think y is 2 because x is -1 right?
207,689= 208,000
Hoped I helped:D
5% = 1/20
so if 35 pages are 1/20th of the book, the book would be 20 x 35 pages long.
20 x 35 = 700 Pages
