Terry drove 366 miles in 6 hours at a constant speed. How long would it take him to drive 427 miles at the same speed

Find his speed by dividing 366 miles by 6 hours:

366/6 = 61 miles per hour.

Divide 427 miles by 61 miles per hour to find the time:

427/61 = 7 hours

The answer is 7 hours.

the answers c

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.
