For the parallelogram, find coordinates for p without using any new variables.
a. (a - c, c)
b. (c, a)
c. (a + c, b)
d. (c, b)

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.
