Answer:
Option 1 is correct.
Step-by-step explanation:
Given the equation 
we have to choose the best statement describes the above equation.
→ (1)
As, the highest degree of its monomials i.e individual terms with non-zero coefficients is 2.
⇒ Degree of above equation is 2.
hence, the given equation is quadratic equation.
The general form of quadratic equation is
In variable u:
→ (2)
Now, compare equation (1) with (2), we say that
The equation is quadratic in form because it can be rewritten as a quadratic equation with u substitution u = (x + 5).
Option 1 is correct.

Step-by-step explanation:
Answer:
9
Step-by-step explanation:
First add 6 to Benjamin's age to make it 18, which is twice Lucas's age. Because it's twice as much, divide 18 by 2 to get 9.
It will take 75 minutes because for one mile it would me 5 minutes 6/30 so 15 miles times 5 would be 75
