Answer:
f(x)=8- 6x
Step-by-step explanation:
2ab - 3a = a.(2b-3)
now the same thing
let's say n=1
a.(2b-3) + n.(2b-3) = (2b-3).(a+n)
Understood?
1. Work out area of rectangle = 9x8=72ft^2
2. Work out base of triangle
13-9=4ft
3. Work out the area of triangle =
4x8=32ft^2 (you don’t need to half it as the base is halved)
4. Add them together=
72+32=104ft^2
Hope this helps
