Which expression shows the distance on a number line between -12 and-1

The distance between A and B = |B - A|

We have -12 and -1.

Substitute:

|-1 - (-12)| = |-1 + 12| = |11| = 11

|-12-(-1)| or |-1-(-12)|

Step-by-step explanation:

If a and b are two points lie on a number line, then the distance between a and b is defined by the expression |a-b| or |b-a|.

We need to find an expression that shows the distance on a number line between -12 and -1.

Here a = -12 and b = -1. So, the distance between -12 and -1 is defined by the expression

On simplification we get

The required expression can be written as  |-1-(-12)|.

Therefore the required expression is |-12-(-1)| or |-1-(-12)|, and the distance between -12 and -1 is 11 units.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
