Jenny lives on washington street. about 8 to 11 cars pass by jenny's house every 15 minutes. which is a reasonable estimate for the number of cars that pass by jenny's house in 105 minutes?

≈66.5 cars in 105 minutes

Step-by-step explanation:

Get average number of cars that pass every 15 minutes (8+11/2) 9.5 cars

15*7=105 hours    

9.5*7   = 66.5 cars in 105 minutes

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.
