Please help!

In a given triangle, the largest side is twice the length of the smallest side.
The other side (that is not the smallest or largest) is 2 units longer than the smallest side.
Which expression represents the perimeter of the triangle if x represents the length of the smallest side? Draw a picture to help you.

A. x+2

B. 4x+2

C. 2x

D. 4x

Answer 1

B. 4x + 2

Explanation:

In the picture provided, it is shown that the side lengths of the sides are:

x, x + 2, and 2x

To find the perimeter, add the side lengths:

x + x + 2 + 2x

2x + 2 + 2x

4x + 2
