Answer: 8 miles</h3>
=======================================================
Work Shown:
x = number of miles
2x = cost of traveling x miles, at $2 per mile, without including the $3 fee
2x+3 = total cost now including the $3 entrance fee, without tip
2x+3+1 = total cost plus $1 tip
2x+4 = amount you spent
2x+4 = 20
2x = 20-4
2x = 16
x = 16/2
x = 8
You traveled 8 miles.
Answer:
GHF and LKM?
Step-by-step explanation:
Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles. The theorem says that when the lines are parallel, that the alternate interior angles are equal
Area of ABC : AB*AC/2
the maximum of the parabola is reached at x=-4/(2*(-1))=2 hence A is at (2,0) and B is at (2,(-2)^2+4*2+C)=(2,12+C)
C is the second root (x-intersect), which we can find :
determinant1 : D=16-4*(-1)*C=4(4+C) thus the second root is at x=

Hence the area of the triangle is

hence

.
We remark that

Hence 4+C=16 thus
C=12
