Calculations ↓
First, let's think of two numbers so that :
- if we multiply these numbers, we'll get 4
- if we add these numbers, we'll get 5
These numbers are :
4 and 1
Plug these numbers here :
(x+4) (x+1)
So the correct factored form of this expression is
Option B) (x+4)(x+1)

It would be: 5/3 * 90 = 150 degrees.........
U have to add all the percentages up which would add up to 1
