Answer:
1 and 3

Answer:
Kim bought 12 sandwiches.
Step-by-step explanation:
In order to find the amount of sandwiches that Kim bought we have to take the total amount she spent on the restaurant (35) subtract the amount she spent on the large potato salad (5) and divide the result by the price of each sandwich (2.5) So we have:
amount spent on sandwiches = 35 - 5 = 30
number of sandwiches = 30/2.5 = 12
Kim bought 12 sandwiches.
You're asking for the square root of 32. you can actually do this on a calculator really easily. just type in the number (in this case, 32) and press the square root symbol (looks like a calculator). the square root of 32 is a long string of decimals, but it's approximately 5.7 :) good luck
