Given:
u varies directly with the square of p and inversely with d.
To find:
The equation for the given situation.
Solution:
If y is directly proportional to x, then

If y is inversely proportional to x, then

It is given that u varies directly with the square of p and inversely with d. So,

It can be written as:

Where, k is the constant of proportionality.
Therefore, the required equation is
.
Answer:
The sum is -8<em>x</em>^2 - <em>x </em>+ 5
Step 1. Divide denominator to numerator .
Step 2. you should have 5.4
Step 3. Keep the denominater (5) and add 5.4 as your numerator. <span />
Combine like terms on left side:
(5f-3f)+(4-2)=2f-2
2f+2=2f-2 subtract 2 from both sides
2f=2f-4 subtract 2f from both sides
0=-4
Since the above in not true,
5f+4-3f-2 does not equal 2f-2 for any value of f....
