Q=2u2 - 5
(d) Find the value of Q when u=-3

Using the figure below, select the two pairs of alternate interior angles.a: point 1 and point 4 b : point 2 and point 3 c: point 6 and point 6d: point 5 and point 7

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.

If a triangle given by the matrix  [2 3 5 -1 0 2]  is dilated by a scale factor of 2, what will happen to the side lengths and angle measures of the triangle
