An arithmetic sequence has this recursive formula:
(a1 = 5
(a^n. = a^n-1 - 4
what is the explicit formula for this sequence?

a. a^n=(-4)+(n-1)5
b. a^n=5+(n-)
c. a^n=5+(n-)
d. a^n=(-1)+(n-)

Me, prove a quadrilateral with vertices g(1,-1), h(5,1), i(4,3) and j(0,1) is a rectangle using the parallelogram method and a rectangle method.

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11

Every weekday, mr. jones bikes from his home to his job. sometimes he rides along two roads, the long route that is shown by the solid lines. other times, he takes the shortcut shown by the dashed line. how many fewer kilometers does mr. jones bike when he takes the shortcut instead of the long route?
