Solve the following inequality. p + 11 < -17

P+11=-17
  -11 =  -11

p    =  -28

The answer is -28

P< -28 

p < - 17 - 11 

move the constant to the right side and change its sign 
 
-17+-11= -28

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.
