Im assuming you mean 2x^2-3x-9=0 ?
If so, you have to factorise the equation
(2x-3) (x+3) = 0
2x - 3 = 0
2x = 3
x = 1.5
x + 3 = 0
x = -3
x is either 1.5 or -3
Answer:
45/10, 4 3/5, 19/4
Step-by-step explanation:
19/4 = 4.75
45/10 = 4.5
4 3/5 = 23/5 = 4.6
4.75 > 4.6 > 4.5
Best of Luck!
Answer:

Step-by-step explanation:
We are asked to find the measure of each exterior angle of a regular dodecagon.
We know that a regular dodecagon is a 12 sided regular polygon with each side equal.
We know that measure of each angle of n-sided regular polygon can be found using formula:

Upon substituting
in above formula, we will get:


Therefore, the measure of each exterior angle of a regular dodecagon is 30 degrees.
