The equation of circle having a diameter with endpoints (-3, 1) and (5,7) is (x- 4)2 + (y - 3)2 = 25
(x - 1)2 + (y - 4)2 = 25
(x - 1)2 + (y - 4)2 = 100

3x+9+4x+x=8x+9that's the answer for your question.

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.
