150 centimeters is equivalent to:
a. 1 meter
b. 1 1/2 meters
c. 750 millimeters
d. 1 yard

All you have to do is divided 150 by  all of those answers and see what your answer is.

Step-by-step explanation:

1.150/1 meter

2.150/11/2

3.150/750 millimeters

4.150/1  yard

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.

c
