You will need 3 cans of paint to cover the two walls
<h3>
How many cans of paint will you need?</h3>
We know that 1 can will cover 200 square feet of wall.
And here we have 2 walls, let's find the total area of these walls.
wall 1 is 20ft by 8ft, then its area is:
A = 20ft*8ft = 160ft^2
wall 2 is 40t by 8 ft, then its area is:
A' = 40ft*8ft = 320ft^2
The total area is:
160ft^2 + 320ft^2 = 480ft^2
The number of cans of paint needed is given by the quotient between the total area and the area that each can cover.
N = 480ft^2/200ft^2 = 2.4
But we can't have a 0.4 of a can, so we should round to the next whole number, which is 3.

The factors of given polynomial are:
Further explanation:
Factorization is either done by using quardatic formula or directly making factor.
For making factors, the constant term is multiplied with the coefficient of x^2 and pairs of factors are made such that their sum or difference is equal to the co-efficient of x.
Given
63x6 gives us: 378
Factor pairs of 378 are:
182,2
126,3
54,7
42,9
14,27 => 41
So the pair we are going to use is 14,27
So the factors of given polynomial are:
