This is my question here: there is an ice cream & candy shop next door that is the same size as your bakery. how many thirtieths of the space does it take up?

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]
