Answer:
C) x2 + x = 306
Step-by-step explanation:
x2 + x = 306
x2 + x - 306 = 0
x2 + 18x - 17x + 18 * (-17) = 0
x ( x + 18) - 17 (x +18) =0
(x + 18) (x - 17 ) = 0
x = -18 or 17
Answer: The car can travel 525 miles on 15 gallons of gasoline.
Step-by-step explanation:
Gas mileage of the car is the number of miles that it can travel on one gallon of gasoline. If the car travels 35 miles per gallon, that means its gas mileage is number of miles travelled / number of gallons of gasoline used.
If the car has 15 gallons of gasoline to travel with, the distance that it can travel would be
Gas mileage of the car × the number of gallons of gasoline it has to travel with. It becomes
35 × 15 = 525 miles
The sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
<h3>Sum of expressions</h3>
Expressions are equations separated by mathematical signs. This expressions are known to contains certain unknowns
Given the following expression
10x^2 +7x+6 and 6x + 5
We are to take the sum of both expression to have:
f(x) = 10x^2 +7x+6 + 6x + 5
Collect the like terms
f(x) = 10x^2 + 7x + 6x + 6 + 5
f(x) = 10x^2 + 13x + 11
Hence the sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
