Answer 1

We know that the perimeter of a rectangle can be represented by the expression 2l +2w, where l represents the length of the rectangle and w represents the width of the rectangle.

If we substitute in the values given in this problem, we get the expression:
2(2x+6) + 2(x)

Another equivalent expression we can use to express the perimeter is w + w + l + l.

If we substitute in the values given in this problem into this expression, we get:

x + x + 2x + 6 + 2x + 6

Overall, we know that these expressions are equivalent and represent the same value (the perimeter of the rectangle), because if you combine like terms, both expressions simplify to 6x + 12.

Hope this helps!
