Answer:

Step-by-step explanation:

The angles are equal. This means that the triangle is equilateral and all the sides are equal to each other.

Set any two sides equal to each other.

2x - 3 = x + 5

x - 3 = 5

x = 8

Now substitute this x value into all the sides and add the numbers up.

2(8) - 3 = 16 - 3 = 13

So we know all 3 sides equal 13.

13 * 3 = 39

Answer: Third option

Step-by-step explanation:

For this exercise it is important to remember the following:

1. By definition, the Associative property of addition states that it does not matter how you grouped the numbers, you will always obtained the same sum.

2. The rule for the Associative property of addition is the following (given three numbers "a", "b" and "c"):

$a + (b + c) = (a + b) + c$

Knowing the information shown before, you can identify in the picture attached that the option that illustrates the Associative property of addition is the third one. This is:

$(11+8)+1=11+(8+1)$
