On friday the temperature was 82 f the temperature changed by -2 on saturday , and then it changed by 5 on sunday , what was the temperature on sunday , explain how the temperature changed using integers

You start off with 82 on Friday, then subtract 2 to find the temperature of Saturday, which is then 80. Once you have Saturday's temperature, you add 5 to it, which is 85. Now you know it is 85 F on Sunday. EQUATION:(82- 2)+5=85

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.
