Which equation is an identity?

–3y + 3 = –3y – 6

3w + 8 – w = 4w – 2(w – 4)

9 – (2v + 3) = –2v – 6

7m – 5 = 8m + 7 – m

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.

A= the square root of 3“if letters are anything like people, they’re all equal and deserve to be treated equally.”
