Simple plug and chug
we know a+b == 6 so replace the set as 6 so:
2(6)+6/6+(6)^2-2
12+1+36-2
49-2
==47
The regular rules of arithmetic apply to function values. Addition and multiplication are commutative, but subtraction and division are not.
The ring operator, signifying a function of a function, is not commutative, either. A simple example can illustrate this:
f(x) = 3
g(x) = x²
(f◦g)(x) = f(g(x)) = f(x²) = 3
(g◦f)(x) = g(f(x)) = g(3) = 3² = 9 . . . . . not equal to 3
The only appropriate choice for Question 19 is ...
A. (f+g)(x) = (g+f)(x)
Answer:
the answer is B
Step-by-step explanation:
5th root of 32 = 2
5 / 5 = cancels
10 / 5 = 2
15 / 5 = 3

Given:
Total length of tape in roll = 16.8 meters
Length of each piece = 1.125 meters
Number of pieces = 8
To find:
The remaining tape.
Solution:
We have,
Length of 1 piece = 1.125 meters
Length of 8 piece = 8 × 1.125 meters
= 9 meters
Total length of tape in roll = 16.8 meters
Remaining tape = Total length of tape in roll - Length of 8 piece
= 16.8 - 9 meters
= 7.8 meters
Therefore, the length of remaining tape is 7.8 meters.
