67.5 mph // 45/2 miles in 1/3 hour times 3 is 135/2 which is 67.5 mph
Answer:

Step-by-step explanation:

Apply natural log property
ln mn=ln m + ln(n), ln(m/n)=ln(m)-ln(n)


All natural log has base 'e'

cross multiply


add 6e^3 on both sides and -x on both sides


Divide e^3-1 on both sides

Givens
h = 10
b = 4x^y + 2xy^2
Formula
Area = 1/2 b * h
Solution
Substitute the givens into the formula
Area = 1/2 * 10 * (4x^2y + 2xy^2)
Area = 5 * (4x^2y + 2xy^2) What to do next? I would remove the brackets
Area = 5 * 4x^2y + 5 * 2xy^2
Area = 20x^2y + 10xy^2 <<<< Answer
Also possible is to take out more common factors.
The common factor of 4x^2y + 2xy^2 is 2xy and what is left over is 2x + y
So you would have Area = 5*2xy(2x + y)
