Solve for x:   [answer1]  A four-sided figure is shown filled with a light blue shading. The top side, labeled from A to B, and the bottom side, labeled from D to C, have matching arrow marks indicating they are parallel. The top-left angle at A is labeled 6x minus 8, and the top-right angle at B is labeled 5x plus 12. The bottom-left angle at D is labeled 5x minus 32, and the bottom-right angle at C is labeled 2x plus 28. The left and right sides slope outward from top to bottom, forming a wider base than top.

Find the scale factor for the dilation shown. Enter any fractions as a/b. A coordinate plane shows two trapezoids, one large in black and one smaller in red. The black trapezoid has vertices G at (-5, 5), Y at (5, 5), V at (10, -5), and R at (-10, -5). The red trapezoid is centered inside, with vertices G′ at (−1, 1), Y′ at (1, 1), V′ at (2, -1), and R′ at (−2, -1). Both shapes have horizontal top and bottom bases and symmetric placement about the y-axis.

Find the value of the variables.  x = [answer1]  y = [answer2]  A four-sided polygon is shaded in yellow. Exterior angles are labeled 10x at the upper right, a right angle at the lower right, 2x at the lower left, and another right anlge at the upper left. The interior angle at the upper right vertex is labeled y°.

Fresh Air recreation company is conducting a survey about people’s favorite outdoor activities.  Which sampling method is most likely to produce a biased result? 

  If A geometric diagram shows two large triangles. The upper triangle has vertices labeled A at the top left, B at the bottom left, and C at the top right. The lower triangle has vertices labeled F at the bottom left, D at the bottom right, and E at the top right. The slanted sides of the triangles run parallel to each other. The vertical sides on the left and right edges appear straight, with A above B on the left and E above D on the right.
