Answer:
42
Step-by-step explanation:
f(3)=2(3)^3-(3)^2-4(3)+9
f(3)=2(27)-(9)-12+9
f(3)=54-21+9
f(3)=33+9
f(3)=42
Answer:
6.8
Step-by-step explanation:
a^2 + b^2 = c^2
6.6^2 + b^2 = 9.5^2
43.56 + b^2 = 90.25
b^2 = 90.25 - 43.56
b^2 = 46.69
(take square root of both sides)
b = 6.8
The factors of 5 are 1 and 5.
1 x 5 = 5
5 x 1 = 5
