Chris made a solid by joining two identical rectangular prisms as pictured below. The overall dimensions of the composite solid are 20 centimeters by 18 centimeters by 15 centimeters. What is the surface area, in square centimeters, of a single prism? A. 465 cm.² B.940 cm.² C. 1200 cm.² D. 1230 cm.²​

Find the value of a. the diagram is not to scale. a quadrilateral is drawn. the upper and lower sides are parallel. the interior angle in the upper left corner is labeled a degrees. the angle in the upper right corner is labeled 113 degrees. the angle in the lower right corner is labeled b degrees. the angle in the lower left corner is labeled 36 degrees. a. 36 b. 144 c. 54 d. 126

Given the points a(-2, 1) and b(8, 6), find the coordinates of the point c on directed line segment ab, that partitions ab in the ration 2: 3.

Which represents the solution set of the inequality 5x-9 < 21? a. x < 12/5 b. x > 12/5 c. x > 6 d. x < 6
