B. Yes
C. No
D. Yes
E. Yes
Step-by-step explanation:
3(x + 2) = 3x + 6
A. 3x + 2 is not 3x + 6
B. 3(2 + x) = 6 + 3x is equal to 3x + 6
C. 3x + 2x is not the same as 3x + 6
D. x + 2x + 2 + 4 = 3x + 6 is equal to 3x + 6
E. x + x + x + 1 + 1 + 1 + 1 + 1 + 1 = 3x + 6 is the same as 3x + 6
Answer:
( the third choice)
Step-by-step explanation:
Let
be the radius of cylinder A and let
be the radius of cylinder B. We assume the heights of both cylinders are the same
Base circumference of cylinder A = 
Base area of cylinder B = 
In order to have
(2) have the same value as
(3) we must multiply by a factor of 
Step-by-step explanation:


Here, the Taylor approximation for a square root was applied, and O(x) stands for all negligible terms of Taylor's sum with respect to variable x.
So, 
b. For an increase of 2%, that is:


4×+9(2×+1)=12kg first you add then multiply
