Hey there! :)
5n(3n - n + 8)
Simplify.
(5n × 3n) + (5n × -n) + (5n × 8)
Simplify.
(15n²) + (-5n²) + (40n)
Remove parenthesis
**Remember : a negative times a positive is always a negative, a positive times a positive is a positive, and a negative times a negative is a positive**
15n² - 5n² + 40n
Combine like terms.
(15n² - 5n²) + 40n
Simplify.
10n² + 40n → final answer :)
~Hope I helped!~
24. Yes, they are congruent by the AAS postulate/statement
26. 3/4.5 = 5.2/a -> m-e thm. -> mult. POC -> a = 7.8 in.
30. pythagorean thm. -> 2² + b² = 2.5² -> b = 1.5 m
32. a) v = 1/3πr²h -> v = 1/3*3.14*4.5²*6 (6 is found w/ pythagorean thm.) -> v ≈ 127.2 cm³
b) yes, 130 cm³ > 127.2 cm³
33. a) 4.5/r = 2/7 -> 4.5/2 = r/7 -> 15.75 ≈ 15.8 in.
b) due to the cones being similar in shape, all one-dimensional measurements will be the same, thus, it is 2:7.
