An equilateral triangle sides are all equal to each other. This means that is one side of an equilateral triangle is x + 3 then the sides of the other two triangles as also each x + 3
The formula for perimeter of a triangle is:
Perimeter = side 1 + side 2 + side 3
Or in the case of an equilateral triangle it would be:
Perimeter = 3(side)
This means that for the formula of this equilateral triangle you have:
Perimeter = 3(x + 3)
If asked the three out side of the parentheses can be distributed, meaning that you multiply the outside number (in this case that is 3) to all the number inside the parentheses (in this case that is x and 3)
Perimeter = (3 * x) + (3*3)
Perimeter = 3x + 9
Both of these are correct:
P = 3(x + 3)
P = 3x + 9
Hope this helped!

Answer:
segment AM
Step-by-step explanation:
A median is a line segment which joins the vertex of a triangle to the midpoint of the opposite side. The median to BC is the vertex opposite it A joined to its midpoint M. The segment AM is the median.
