Geoffrey and his babysitter spent 32 minutes eating dinner. if they finished dinner at 7: 48 p. m., what time did they start eating?

They started eating at 7:16 PM

They would have started dinner at 7:16 if they finished at 7:48, and ate for 32 minutes. hope this helps.

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.
