Using the midsegments of the triangle in the image below, what is the perimeter of АВС?
Give your answer as just a number.
Please help I’m desperate. I just don’t get it.

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Which best explains why this triangle is or is not a right triangle?
