Triangle abc has vertices a (1,5) b(9,7) and c (7,13) m is the midpoint of line ab and n is the midpoint of bc. what is the length of mn

Find the total area for the regular pyramid ( follow the answer set up in the picture)

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)
