Three balls will be needed. You will need 70 pieces of the 40 cm string so 70 multiplied by 40 equals 2800. Next you need to convert the 2800 cm into meters and 2800cm= 28 meters, so if each ball of string is 10 meters long you will need 3 of them which will give you 30 meters so you will have enough with a little extra. Hope this helped!
Answer is choice C
"Dilate with a scale factor of two" means "multiply each coordinate by two"
A = (2,3) turns into A' = (4,6)
B = (3,5) turns into B' = (6,10)
C = (7,4) turns into C' = (14,8)
Side Note: this quick shortcut only works if the center of dilation is the origin (0,0). If the center of dilation isn't the origin, then you will have to do a translation (shifting) before you can use the trick, and then you'll have to shift back. The idea of the shifting is so that the center of dilation becomes the origin on a temporary basis. Because no mention is made of the reference center, it is assumed to be the origin by default.
