Answer:
Formular for coordinate length:

In considerance of coordinates given of A and B

therefore substitute:

Given:
nine 5 pound bags
distributed into 10-ounce bags
1 pound = 16 ounces
9 x 5 pounds = 45 pounds
45 pounds * 16 ounces/lbs = 45 * 16 oz = 720 ounces
720 ounces / 10 ounce bags = 720/10 = 72 bags.
The workers at the food pantry will be able to make 72 bags.
You have to substitute 3+h for x, then work out the equation.
(3+h)^2 + 3(3+h) + 5 = 9 + 6h + h^2 + 9 + 3h + 5 =
h^2 + 9h + 23
Answer B.
