In the figure below, the segment is parallel to one side of the triangle. find the value of x.

Which graph corresponds to the function f(x) = x2 + 4x – 1?

Anna is constructing a line segment that is congruent to another segment ab. for the construction, which tool should be used to mesure segment ab
