Question

Three sides of a quadrilateral are the same length, g, The length of the fourth side is 7 inches,

The perimeter of the quadrilateral is 10 inches,
Write an equation that represents
the situation
7
3
7

Answer 1

Explanation:

Let s represent the length of each of the three sides mentioned. The length of the fourth side is 7 inches. Adding the lengths of the four sides together yields 10 inches: g + g + g + 7 = 10 (inches)

Then 3g + 7 = 10, or 3g = 3, or g = 1.

This equation is OK, but there's no solution, since 3g or just 3 is less than 7. With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.
