A number, n, is added to 15 less than 3 times itself. The result is 101. Which equation can be used to find the value of n?
O 3n - 15 + n = 101
3n + 15 + n = 101
3n - 15-n = 101
3n + 15 - n = 101

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.
