Stop & Shop is having a sale on paper towels: 5 rolls for $3. How much will 7 roll(s) cost?

Which problem could be  solved  by evaluating the expression  7×(−3)7×-3?

What is the least common multiple of 6 and 17?

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.
