Well if I did the right calculations... Kim is 24. The sister is age twelve! Hope I helped.

A. K+S=36

B. Well Simple Addition and Subtraction solves this easily. If you Add 12+12 it equals 24. It still needs to be larger so that Kim is twice as old as her little sister. So you Add another 12 which gives you 36. Or you can easily subtract 12 from it and that will also bring you to 24.

(05.05)Polygon ABCD has the following vertices: A(−5, 4), B(1, 4), C(6, −4), and D(−5, −4) Calculate the area of the polygon.
ella [17]
The first thing you should do is draw the points in the Cartesian plane and then join them to find the polygon.
 The searched polygon can be seen in the attached image.
 The area of the polygon will be the area of the square plus the area of the triangle.
 At = (6) * (8) + (1/2) * (5) * (8) = 68
 At = 68
 answer
 the area of the polygon is 68units ^ 2
