To simplify the expression we are going to use the distributive property of multiplication: 
.
We can infer from our problem that
, 
, and 
. So lets apply the property to simplify our expression:
We can conclude that the correct answer is <span>-8x3 + 6x2</span>

We can conclude that the correct answer is <span>-8x3 + 6x2</span>
For this case we have the following conversions:
We must apply the conversions to move from kilometers to feet.
We have then:
Rounding off we have:
10501 feet
Answer:
there are 10501 feet in 3.2 km

Answer:
Sum of the Roots = 37
Product of the Roots = 27
Step-by-step explanation:
Here, the given expression is
Now the general Quadratic Equation is of the form:
Here, Sum of the Roots =
and the Product of the Roots =
So, comparing the general equation with the given equation, we get:
a = 1, b = -37 and c = 27
So, Sum of the Roots = = 37
and the Product of the Roots = = 27
