Calculate the area of triangle DEF

The graph below shows the price of different numbers of mats at a store: a graph is shown. the values on the x axis are 0, 2, 4, 6, 8, 10. the values on the y axis are 0, 21, 42, 63, 84, and 105. points are shown on ordered pairs 0, 0 and 2, 21 and 4, 42 and 6, 63 and 8, 84. these points are connected by a line. the label on the x axis is number of mats. the title on the y axis is price in dollars. which equation can be used to determine p, the cost of b mats?

Factor p 2 + 18p + 32. (p+ 4)(p + 8) (p + 2)p+ 16) (p + 16)2

Select the correct answer from the drop-down menu. this graph represents the inequality x+2< 4,2x> 3,x+6< 12,2x> 12
