Me ! will give brainliest or whatever it’s called lol

The vertices of a triangle are a(7,5), b(4,2), c(9,2). what is m

Select the graph of the solution. click until the correct graph appears. |x| = 3

Simplify (4x^2 - 8xy + 2y^2) - (9x^2 - 4xy - 7y^2) a. -5x^2 + 4xy + 9y^2 b. -5x^2 - 4xy + 9y^2 c. -5x^2 + 12xy + 4y^2 d. -5x^2 - 4xy - 5y^2
