Problema Solution
A Square window has a perimeter of (8x + 12)feet. Write an expression that represents the side length of the window (in feet).
Answer provided by our tutors
Let 'a' represent the side length of the square window.
The perimeter of the square window can be calculated by the formula P = 4a.
We also know that P = 8x + 12 thus we have:
4a = 8x + 12 divide both sides by 4
a = 2x + 3
The expression that represents the length of the window's side is: 2x + 3.
