Question The vertices of a trapezoid are A(−2,3),B(2,3),C(5,−2), and D(−2,−2). Dilate the trapezoid with respect to vertex A using a scale factor of 2. What are the coordinates of the image?

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

You need to do x2-x1,y2-y1 and divide it by 2 and you should get (1,-3)
