15. 1, 3, 5, and 7 are odd numbers, and 1 = 0 + 1,3 = 1 + 2,5 =
2 + 3, and 7 = 3 + 4.
a. find the next three equations that continue the pattern.
b. make a conjecture about a property of odd numbers.
c. what type of reasoning did you use?

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

Kevin is an insurance salesman. when he sells a policy, he makes 20 percent of the policy premium (p) up front; then each year the policy is active, he receives 15 percent of the original premium. which equation could be used to figure his total commission on a policy that has been active for five years? c=0.80p c=0.20p + 0.15p c=0.35p + 4(0.15) c=0.95p

Two streets intersect at a 30- degree angle. at the intersection, the are four crosswalks formed that are the same length. what type of quadrilateral is formed by the crosswalks?
