Step-by-step explanation:
speed = distance/time
we know the speed and the time (11:45am to 1:45pm = 2 hours).
distance = speed × time = 56 m/h × 2 h = 112 miles
12x - 13 - x - 9 + 10x
First, get the like terms together
12x + 10x - x -13 -9
Now, combine like terms
12x + 10x - x = 21x
-13 - 9 = -22
Final Answer:
21x - 22
Given:

Find-:
Factorization of the equation.
Sol:
A simple method of factorization is to multiply in first and last order then break it down into parts to make the middle number then.

The factor of 99 is:
So take factor :
