The two numbers are -18+ 2√(11) and -18 -2√(11).

-18+ 2√(11)+ [-18 -2√(11)]= -36
[-18+ 2√(11)]* [-18 -2√(11)]= 280.

Hope this helps~

Answer:

If there are 2 quarters for every 3 nickels,

then there are $45*\frac{2}{3} =30$ quarters.

If there are 2 dimes for every quarter,

then there are $30*2=60$ dimes.

If the number of pennies and nickels together are equal to the number of dimes, then there are $60-45=15$ pennies.
