The Cubic Polynomial  given here is

x³ - x² - x -3 =0

Rational root theorem :

Consider any polynomial

→ Ax^n +A_{1}x^{n-1}+A_{2}x^{n-2}+.................+A_{n}=0

So, the factors of this polynomial is those number which divides \frac{A_{n}}{A}.Which are \pm1, \pm\frac{A_{n}}{A}

Applying the same method the number which divides (-3) are,-3,+3,-1,+1. So By rational root theorem all the factors of this cubic polynomial is \pm1,\pm3.

Option 1. -3,-1,1,3 is correct option.

t takes about 14 person-hours of labor to break up a driveway and clear away the rubble. It takes about 8 person-hours of labor
Ostrovityanka [42]
For this case what you must do is add the number of hours to perform the different activities.
 We have then:
 14 person-hours of labor to break up to driveway and clear away the rubble.
 8 person-hours of labor to pour and smooth concrete for the new driveway.
 Adding both activities we have
 14 + 8 = 22
 answer
 it takes to break up to driveway, clear away the rubble, pour the concrete, and smooth the concrete about 22 person-hours of labor

Suppose that a cylinder has a radius of r units, and that the height of the cylinder is also r units. The lateral area of the cy
horrorfan [7]

Answer:

r = 7.33 units

Step-by-step explanation:

Given that,

A cylinder has a radius of r units, and that the height of the cylinder is also r units.

The lateral area of the cylinder is 338 square units.

We need to find the value of r.

The formula for the lateral area of the cylinder is given by :

A=2\pi rh

Put all the values,

2\pi r^2=338\\\\r=\sqrt{\dfrac{338}{2\pi}} \\\\r=7.33\ unit

So, the value of r is equal to 7.33 units.
