Question

write a polynomial that represents the area of the square. 13. 7n - 5

Explanation:

Step1: Recall the area formula for a square

The area \( A \) of a square is given by the formula \( A = s^2 \), where \( s \) is the length of a side of the square.

Step2: Substitute the side length into the formula

In this problem, the side length \( s \) of the square is \( 7n - 5 \). So we need to square this binomial. Using the formula \( (a - b)^2 = a^2 - 2ab + b^2 \), where \( a = 7n \) and \( b = 5 \):
