Write an equation in standard form for the circle shown. A) (x + 3)2 + (y – 1)2 = 7 B) (x - 3)2 + (y + 1)2 = 7 C) (x + 3)2 + (y – 1)2 = 49 D) (x - 3)2 + (y + 1)2 = 49

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.

pretty sure its b

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
