Boston can be very cold at -3 degrees Fahrenheit. If the temperature continues to drop at a constant rate for four days, what is the temperature at the end of the fourth day?

It depends what the constant rate it bt if it is -3 the it would be -3x4=12 and then -3-12=-15

Step-by-step explanation:

-15

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.

i believe the answer is c.
