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.

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.

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

if x decreases by 4 then y increases by 10
