Question

The perimeter of the square is 4(x+3), and the perimeter of the triangle is 3(3x-1). Because the perimeters are the same , 4(x+3) = 3(3x+—1). Try substituting 3 for x in the equation. Do you get a true statement? Explain.

Answer 1

Answer:

Yes.

Step-by-step explanation:

When you put in a 3 for x, your equation becomes 4(3+3)=3(3(3)-1). This can be simplified to 4(6) = 3(8) so 24 equals 24, which is true.
