PLEASE WILL MARK BRAINLIEST A single-engine plane is flying at 30 mph in the direction N 60° E. A wind is blowing from west to east at 15 mph. Which diagram accurately represents the wind triangle for this plane?

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.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
