Answer: 
Write the equation in standard form: 
.
Use the quadratic formula. <em>(+-) = </em>±
Substitute in the values, where a = 3, b = 4, and c = -20, and simplify.
The escape velocity on Mars' moon Phobos is about 11 m/s, or 25 mph. The body's mean diameter is 11 km (6.8 mi). Its smaller cousin, Demos, with a mean diameter of 6 km (3.7 mi), has an escape velocity of only 6.9 m/s (15 mph), meaning that you could probably jump right off it if you tried hard enough.
Answer:
Step-by-step explanation:
Degree is the highest exponent on the variable in a polynomial.
A leading coefficient is the first terms coefficient when the polynomial is written in standard form.
To write this polynomial, write 
as your first term. Its leading coefficient is -4 and it has a degree of 3. Then add whatever terms after it being sure to not add any more with exponent 3 or higher.
Example:
40 mi² is your answer
They are 4 equal rectangle.
Area rectangle = w * l
5 * 2 = 10 mi² (area 1 rectangle)
then you multiply by 4
10 * 4 = 40 mi²
or
5 * 2 * 4 = 40 mi²
These numbers would be -5 & 6...
(-5)(6) = -30
-5 + 6 = 1
