What is the next term of the sequence -3, 6, -12, 24, que

-48

Step-by-step explanation:

next in a row  is always equal previous one multiple by -2

-3*(-2)=6

6*(-2)=-12

-12*(-2)=24

24*(-2)=-48

a) what number, when added to negative four, is equal to negative five?

step-by-step explanation:

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.
