Idon't understand how to do number 14. !

Since both points are on the x- axis the equation of the line would be y= 0.

So the equation to setup is y1-y2 /x1-x2=y/x so y1 is 0 minus y2 which is 0 which equals 0 over x1 which is -3 minus x2 which is 0 equals -3 and so the answer would be 0 over -3 or in graphing points(-3,0)

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
