Write the equation 2x 2 - 4x + 6 = 1 in standard form and then choose the value of "c."
2 answers:
Answer:
c = 5
Step-by-step explanation:
Given equation
We have to Write the equation in standard form and then choose the value of "c."
The standard form of the quadratic equation is given as , where a , b and c are the coefficients.
Consider the given equation
Subtract 1 both sides, we have,
simplify, we have,
Now on comparing with standard form we get,
a = 2 , b = -4 and c = 5
Thus , c = 5

so the rectangular prism, or that box, is really just 6 rectangles stacked up to each other at the edges, notice
front and back are just two 9x5 rectangles
left and right are just two 5x4 rectangles
top and bottom are just two 9x4 rectangles
get the area of all 6, sum them up, and that's the area of the box.

Answer:
<h3>4m² + 6mn - 2n²</h3>Step-by-step explanation:
Answer:
The hikers A and B travel at rates of 1.1 miles per hour and 3.3 miles per hour, respectively.
Step-by-step explanation:
Let suppose that each hiker travels at constant speed, such that kinematic formulas are, respectively:
Hiker A
Hiker B
Relationship
(They walk toward each other)
Where:
,
- Initial and final position of the hiker A, measured in miles.
,
- Initial and final position of the hiker B, measured in miles.
- Time, measured in hours.
,
- Velocities of hikers A and B, measured in miles per hour.
Given that ,
,
and
, the system of equation is reduced to the following:
Now, the velocity of the hiker A is:
The hikers A and B travel at rates of 1.1 miles per hour and 3.3 miles per hour, respectively.
