2k(1+5a) <em>or </em>2k(5a+1)

First of all, let's find the common term of this binomial (an expression with two terms; the prefix bi- means "two")
Note that both terms have 2k in them. So, we factor it out.

<em>Simplify</em>
<em />
<em>2k can't just vanish into thin air, so we put it outside the parentheses:</em>

<em>Great job! We factored the expression successfully</em>

Hope that this helped! Best wishes.

of a single roll . Mr. Hanky have 5 roll so Total Area =
. So ,
paper does Mr. Hanky have
<u>Step-by-step explanation:</u>
Here we have , Mr. Hanky has 5 rolls of butcher paper. If you roll out a whole roll the paper would measure 510 yards long. If the paper is 1.8 yard wide .We need to find that how many total square feet of paper does Mr. Hanky have . Let's find out:
We know that when butcher paper will be unfolded it will be in form of a rectangle with dimensions as :

So , Area of rectangle = 
⇒ 
⇒ 
⇒ 
But , 
⇒ 
⇒ 
Therefore ,
of a single roll . Mr. Hanky have 5 roll so Total Area =
. So ,
paper does Mr. Hanky have .
