So 11 times 2=22 so you times 11 times 2 on all sides so the answers is 22
Reduce the index of the artical and exponent with 2 and get 3x18a. Calculate the product and get 54a.
30% of 40 = 0.30(40) = 12......so 12 tables seat 4 people per table = 12 x 4 = 48 seats.......tables remaining seat 22 people (22 seats).
48 + 22 = 70 seats total
