Answer: 
Step-by-step explanation:
The Greatest Common Factor (GCF) of a polynomial is defined as the largest monomial that is a factor of all the terms of the polynomial.
In this case, given this polynomial:

You can factor out the Greatest Common Factor applying this procedure:
1. Write the terms of the polynomial in prime factor form:

2. Identify the factors the terms have in common (this will be the Greatest Common Factor). In this case this is:

3. Finally, rewrite the expression in factor form:

Answer:
1. GH
2. a
Step-by-step explanation:
Perpendicular: When 2 lines meet at 90 degrees
1. It is line segment GH because AB and GH meet at a 90 degree angle (since there is a box at angle GHF indicating that it is 90 degrees)
2. It has to be a units because it is a rectangle where the top and bottom are congruent and the sides are too
This is a rectangle since AB and CD are parallel and GH can be a transversal line, according to same side interior angles theorem EGH is a also 90 degrees. That means FEG is 90 degrees too because then the quadrilateral will add up to 360 degrees
Answer:
= 2n²
Step-by-step explanation:
From the sequence 2,8,18,32,50
The difference between each numbers are
: 6, 10, 14, 18
The difference between the second sequence is 4.
Therefore the nth term of the sequence is 2n²
