Answer:
3.5 miles
Step-by-step explanation:
From the question, we have the following information:
The super speedway at Daytona International Speedway is = 2.5 miles
long
The road course there is = 1.4 times as long as the super speedway.
How long is the road course?
The length of the road course is calculated as:
1.4 × length of the super speedway
1.4 × 2.5 miles
=>3.5 miles
Therefore, length of the road course I s 3.5 miles.
Answer:
No, it is incorrect.
Step-by-step explanation:
The quadratic equation is
or . To complete square we take the coefficient of x divided by 2, square that value and add the result to both sides. In the equation given the number to do the process is 20, not 6, then the solution method is incorect.
Answer:
NO it is not correct
Step-by-step explanation:
Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
