True [87]3 years ago
8 0

Answer:

\dfrac{5x^2-3x+8}{2x+1}

Step-by-step explanation:

The denominators are the same, so the numerators can be added in the usual way.

... = ((5x^2 +6) -(3x -2))/(2x +1)

... = (5x^2 +6 -3x +2)/(2x +1)

... = (5x^2 -3x +8)/(2x +1)

The numerator and denominator have no common factors, so this cannot be reduced further.

IN ΔBCD line N is the perpendicular bisector of BC and line M is the perpendicular bisector of CD
Helga [31]

Answer:

Correct answer is D(the intersection of lines N and M)

Step-by-step explanation:

we Know that  circumcenter of a triangle is  point at which the perpendicular bisectors of the sides of a triangle intersect and which is equidistant from the three vertices. In other words circumcenter of a triangle is the center of the circle which  passes through the vertices of the triangle. It means, any side of the triangle will act as a chord of the circumcircle. Hence the circumcenter of a triangle must lie on the perpendicular bisectors of the sides. therefore the intersection of line N and M must be  circumcenter of the triangle.

I hope this answer will help you

The shortest route from London to York is 200 miles.
vovikov84 [41]

Answer: The lorry is traveling 10 mph over the expected speed.

Step-by-step explanation:

If 200 miles takes 4 hours, the speed is 200mi/4hr which  is 50 mph.

If the distance is increased by 20%, the distance is 240 miles.

240mi/4hr = 60mph

The difference is 10mph
