By using shadows, Megan wants to find the height of a flagpole. At a certain time of day, her shadow is 3.5 feet long and the flagpole’s shadow is 14 feet long. Her height is 5.5 feet. How tall is the flagpole?

the pole is 22 feet long

Multiply the length of the flagpole's shadow by meagan's height, and then divide the resulting number by the length of  her shadow.

For example, if you are 5 feet tall, your shadow is 8 feet long, and the tree's shadow is 100 feet long, the height of the tree is (100 x 5) / 8 = 62.5 feet.

I hope its right because I kind of took a good guess. If ur not sure with my answer then i suggest u dont put it unless u are.

good luck!

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.
