Sent a picture of the solution to the problem (s).
14. -15 degrees celsius
15.
- Boys = 15 * 3 = 45
- Total = 15 + 45 = 60
16. 2(5)^2 + 5 = 2(25) + 5 = 50 + 5 = 55
Use the Pythagorean Theorem to find the length of the line segment connecting (4,-6) and (9,-5). The change in x is 5 and the change in y is 1. Thus, the
hypotenuse is sqrt(5^2 + 1^2) = sqrt(26) (answer).
