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.
Answer:
x = - 16
Step-by-step explanation:
Given
x + 7 = - 9 ( subtract 7 from both sides )
x = - 16

Answer:
900
Step-by-step explanation:
To get your answer, you can just multiply 20 seconds by 3 to get 60 seconds, which is a minute.
Since whatever you do on one side you have to do to the other, multiply 300 mi by 3 as well. That would get you 900.
