(3x^2-4x+5)+(-2x^2+x-6)

x² - 3x - 1

Step-by-step explanation:

First, get rid of the parenthesis you dont need.

3x² - 4x + 5 + (-2x²) + x - 6

Now, you subtract and simplify the variables with the same term.

3x² - 2x² - 4x + x + 5 - 6 (this is for a better visual)

x² - 3x - 1 (final answer!!)

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
