7X(-3)X(-2)^2=?
I suck at math

The rows and columns of lattice points in a three-by-three square array are evenly spaced one unit apart. how many distinct triangles with at least one side of length 2 units can be drawn using three lattice points for the vertices?

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

What is the slope of the line shown below?
