Question

In geometry the four sides of a square are all the same length. One side measures (3x+4) 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 1

Explanation:

We can set up an equation:

4(3x+4)=76

We can distribute the left side and get:

12x+16=76

Subtract 16 from both sides:

12x=60

Divide 12 from both sides:

x=5

Check:

4(3*5+4)

4(15+4)

4(18)

76

So x=5
