7. Nick put two trapezoids with the same dimensions together to make a parallelogram.
The formula for the area of a trapezoid is A= ž (b, + b )h.
Explain why the bases of a trapezoid need to be added in
the formula.

Write the linear inequality shown in the graph. the gray area represents the shaded region. y> -3y+5 y> 3x-5 y< -3x+5 y< 3x-5

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Does the point (1, sqrt 7) lie on circle shown.
