In geometry the four sides of a square are all the same length. One side measures (3x+4)?

Question

and the perimeter of the square is 76.Find the value of X. Hint: First set up an equation to help you solve for X.

Answer

Perimeter is the sum of all sides, so one side = 19.

3x + 4 = 19  The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4.

3x = 15  Divide by 3.

x = 5  <--  ANSWER

Answer

4 * (3x + 4) = 76
12x + 16 = 76
12x = 60

x = 5.
