In the given question, most of the information's are of immense importance. based on these information's, the required answer to the question can be found. It is already given that the car releases 19.6 pounds of carbon dioxide for 1 gallon of gasoline. The amount of carbon dioxide released for 14.5 gallons of gasoline needs to be found.
So
Amount of carbon dioxide released by
1 gallon of gasoline = 19.6 pounds
Then
Amount of carbon dioxide released by
14.5 gallons of gasoline = (19.6 * 14.5) pounds
= 284.2 pounds
So an estimated 284.2 pounds of carbon dioxide will be released by 14.5 gallons of gasoline.
Answer: The length is 6 feet and the width is 10 feet.
Step-by-step explanation: The question has specified the area as 60 (square feet) and the length and width are yet unknown. However we know that the length is 4 feet less than the width. What this means is that, if the width is W, then the length is W - 4.
We can now write an equation for the area of the rectangle as follows;
Area = L x W
60 = (W - 4) x W
60 = W^2 - 4W
If we rearrange all terms on one side of the equation, we now have
W^2 - 4W - 60 = 0
This is a quadratic equation and by factorizing, we now have
(W + 6) (W - 10) = 0
Hence,
Either W + 6 = 0 and then W = -6
Or W - 10 = 0 and then W = 10
We know that the side of the rectangle cannot be a negative value, so we go with W = 10.
Having calculated W as 10, the length now becomes
L = W - 4
L = 10 - 4
L = 6
Therefore, length = 6 feet and width = 10 feet
Answer:
(x-3)(x-2)
Step-by-step explanation:
x^2 -5x+6
What two numbers multiply to 6 and add to -5
-3 * -2 = 6
-3 -2 = -5
(x-3)(x-2)
