Answer:
Please check the explanation.
Step-by-step explanation:
Given
a)
f(x) + g(x) = (2x - 1) + (2 - x)
= 2x -1 + 2 - x
= x + 1
b)
f(x) - g(x) = (2x - 1) - (2 - x)
= 2x - 1 - 2 + x
= 3x - 3
c)
g(-5) - f(-5)
Putting x = -5 in g(x) = 2 - x
g(x) = 2 - x
g(-5) = 2 - (-5) = 2+5 = 7
Putting x = -5 in f(x) = 2x - 1
f(x) = 2x - 1
f(-5) = 2(-5) - 1
= -10 - 1
= -11
Thus,
g(-5) - f(-5) = 7 - (-11) = 7+11 = 18
d)
f(x).g(x) = (2x - 1) (2 - x) = -2x² + 5x - 2
e)
f(g(x)) = f(2-x)
= 2(2-x)-1
= 4-2x-1
= 3-2x
Answer: = 8

Answer:
1.6022x 10-19
Step-by-step explanation:
1.6022x 10-19 then simplifies into 16.022 because of the 10, and then the final answer is -2.978
Answer:
4b² - 16
Step-by-step explanation:
The formula to find the area of a parallelogram equals 
, where b = base and h - height. We're given the base as 2b + 4 and the height as 2b - 4.
Therefore, the answer is 4b² - 16.
Answer:
D. 27:1331
Step-by-step explanation:
The volume ratio for the two solids is the side length ratio raised to the third power.
3 to the 3rd power = 27
11 to the 3rd power = 1331
