Answer:
volume = x(x+2)(2x+1) = 2x^3+5x^2+2x
a = 2
b = 3
c = 5
d = 2
e = 2
f = 1
Answer:
40° and 140°
Step-by-step explanation:
A linear pair of angles sum to 180°
let x be one angle then the other is 3.5x and summing gives
x + 3.5x = 180
4.5x = 180 ( divide both sides by 4.5 )
x = 40
one angle = 40° , the other is 3.5 × 40° = 140°
use rise over run to solve your answer
