The answer is 
.
Solution:
Use algebraic identity: 
For example: 
Given expression 
and 
.
To multiply these equations.
Combine like terms together.
Hence the answer is .
The slope of the line is -4
Undistribute z
divide both sides by (v-k^5)
Answer: 25.13 m
Step-by-step explanation: pi x 2^2x 6= 25.13
3
This is an approximate number but it should be correct
:)
1) We have to calculate the first derivative:
y=2x²+2
y´=4x
2) the slope at the point x=3; will be f´(3);
f´(3)=4(3)=12
answer: the slope will be 12.
