Answer:
The width of the area model is equal to

Step-by-step explanation:
<u><em>The complete question is</em></u>
Todor was trying to factor 10x^2-5x+15 he found the greatest common factor of these terms was 5 what is the width
we know that
The area of a rectangular model is given by the formula
----> equation A
where
L is the length
W is the width
we have

Factor the expression
substitute the value of the Area in the equation A

In this problem
The greatest common factor of these terms is the length (L=5 units)
so
we can say that the width is equal to (2x^2-x+3)
therefore
The width of the area model is equal to

1. HI Because two parallel lines have to be on the same plane and never intersect.
2. Skew means the never intersect and they aren't on the same plane so it is GK and DH
3. Angle 3 corresponds because it is the bottom left and 7 is the bottom left.
4. 3 and 5 are same-side interior because they are both on the left side and both are inside.
Hope this helps!
