C= 3 because you subtract 2 on both sides, which is 2c= 6 then you divide 2 on both sides to get c= 3 haha

In equilateral triangles STU:

Len [333]

<h3>Answer: B) 39</h3>

==========================================================

Explanation:

Equilateral triangles have three equal sides, ie the sides are all the same length.

Let's set sides ST and TU equal to each other and solve for x

7x-10 = 2x+25

7x-2x = 25+10

5x = 35

x = 35/5

x = 7

Then we use this to compute each side

ST = 7x-10 = 7*7-10 = 49-10 = 39
TU = 2x+25 = 2*7+25 = 14+25 = 39
US = x^2 - 10 = 7^2 - 10 = 49-10 = 39

Each side is 39 units long, so this confirms we have the correct answer.
