Answer:

(b+1)^2(b+6)

Step-by-step explanation:

The given rational expression is:

\frac{b}{b^2+2b+1}-\frac{6}{b^2+7b+6}

We factor the denominators to get:

\frac{b}{(b+1)^2}-\frac{6}{(b+1)(b+6)}

The least common denominator is the product of the highest powers of the common factors of the denominators.

Therefore the least common denominator is:

(b+1)^2(b+6)

Name the conic section formed when a plane cuts a right circular cone parallel to its base.
gregori [183]

Answer:

option 1.

circle

Step-by-step explanation:

A section is formed when a solid shape is sliced into two. A conic section is therefore formed when a cone, is sliced into two.

What determines the shape of the section now, is the angle at which the cone was sliced.

Normally, the base of a cone is a circle.  If we slice a cone using a straight line, which runs parallel to its base, we will still get another perfect cone, but with a smaller height.

If we look at the flat portion of the cone after it has been sliced, we will see that the cross-section is a circle.

As you leave? Clark, the sign says Lutherville 150 ?miles, Otisburg 240 miles. If the Planet Diner is halfway between Luthervill
eimsori [14]

\bf Clark\rule[0.35em]{7.8em}{0.25pt}\stackrel{150}{Lutherville}\rule[0.35em]{4em}{0.25pt}Planet Diner\rule[0.35em]{4em}{0.25pt}\stackrel{240}{Otisburg}


the distance between Lutherville and Otisburg is 240 - 150 = 90.

Planet Diner is half-way between them, half of 90 is 45.

Planet Diner is 45 miles from Lutherville.

from Clark to Lutherville is 150 miles, and from Lutherville to Planet Diner is 45 miles, thus from Clark to Planet Diner is 150 + 45 = 195.
