Question

Find the length of ST. St= 5x+2 and TV = 3x+12
Thank you for anyone who does answer(:

Answer 1

I think you forgot to include that T is the midpoint of SV, but what this would mean is that ST = TV.
5x + 2 = 3x + 12

Subtract 2 from both sides.
5x = 3x + 10

Subtract 3x from both sides.
2x = 10

Divide both sides by 2.
x = 5

Now plug that x into ST.
ST = 5(5) + 2
ST = 25 + 2
ST = 27
