Factor
9c^4-21c^2+21c^2-49
Final answer: 9c^4-49
If M is a midpoint of PQ, then we can use the formula of a midpoint:

We have the endpoints (-2a, 0) and (0, 2b). Substitute:

<h3>Answer: M(-a, b)</h3>

what is the question
Answer:
5 sqrt(3) =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 30 = x/15
15 tan 30 = x
15 ( sqrt(3)/3) = x
5 sqrt(3) =x
Answer:
The measure of angle ABC = The measure of angle A prime B prime C prime
Step-by-step explanation:
we know that
The transformation of the figure is a reflection, so after the transformation the shape still has the same size, area, angles and line lengths.
the triangles ABC and A'B'C' are congruent
therefore
the corresponding sides and corresponding angles are equal
so
The relationship between the measures of the angles of the two triangles is
