Xin uses 20 yards of fencing to build the walls of a square chicken coop. Which equation and solution represent x, the length, in yards, of each wall of the square coop?

4x=20

X=5

Step-by-step explanation:

To find x, you divide 20 by four, which gives 5 as an answer

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

tube or goog would be a great resource to with that question
