If AABC is dilated by a scale factor of 2 with a dilation center of A, what will be the coordinates of point B'? A)
(0,0)
B)
(0, 3)
(0,4)
D)
(0,6)

the image of (6, 9) under a dilation is (4, 6). the scale factor is

b. 2/3

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.
