On the map, 1 inch represents 100 miles. approximately how many miles is it from mackinac bridge to green bay? you may use your own ruler to approximate the distance between the two cities. (for accurate measurement, your screen's zoom should be set so your ruler matches the ruler shown.)

150 miles

Step-by-step explanation:

The distance between the two is about 1.5 inches.  Since 1 inch on the ruler represents 100 miles, we can write a proportion:

100 miles / 1 inch = x miles / 1.5 inch

x = 150 miles

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.
