All of the angles on a triangle add up to 180 degrees.
4 3/8 I think that is correct.
a - side of the square
4a - the perimeter of a square
76 in - the perimeter of a square
The equation:
4a = 76 <em>divide both sides by 4</em>
a = 19 in.
<h3>Answer: Each side has length 19 inches.</h3>
(-4x + 18) - (2x - 7) Multiply/distribute the - into (2x - 7)
-4x + 18 - 2x + 7 Combine like terms
-6x + 25
