Choose one of the factors of 6x^3 + 6
ivanzaharov [21]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

6x^3+6

Now, by factorising , we get

6x^3+6\\=6(x^3+1)

Now, we use the formula i.e.

a^3+b^3=(a+b)(a^2-ab+b^2)

By using this, we get ,

6(x^3+1)\\=6(x+1)(x^2-x+1)

So,

(x+1) \text{ is the factor of }6x^3+6.

3. Define a variable, write an equation, and solve the problem. Carla began a
faust18 [17]

Answer:

Carla has been running 7 miles each day for 13 days.

Step-by-step explanation:

Carla ran 3 miles on her first day, 5 miles on her second day and then 7 miles each day onward.

Let the number of days she ran 7 miles each day = x

Total distance run by Carla = 3 + 5 + 7(x)

                                             = 8 + 7x

If her log book shows that she has run total distance = 99 miles

Equation representing her total run will be,

8 + 7x = 99

7x = 99 - 8

7x = 91

x = \frac{91}{7}

x = 13 days

Therefore, Carla has been running 7 miles each day for 13 days.

What is the best description for the lines
jeyben [28]

Answer:

Lines are described as connecting curve joining two points.

Step-by-step explanation:

In coordinate geometry, graph theory, we have points which do not occupy any space.

Any two points can be connected by a curve or a straight line.  If two points are joined by a straight line, then we have the slope of the line i.e. the tangent of angle of the line with x axis is constant.

Straight lines would be of the form ax+by+c=0

Hence in equation form, lines would have equations in linear form of both x and y.

Lines have constant slope throughout the region.

Lines can be extended from -infinity to +infinity

Any two distinct  points can make a line, but 3 points need not lie on the same line.
