13 feet

Step-by-step explanation:

All sides of a square are the same length.

If we call each side of the square 's', then the formula for the area of the square is A = s×s = s2.

The problem states the area is 169 square feet.

A = s2

169 = s2

Take the square root of both sides.

13 = s

Each side of the court is 13 feet!

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
