Answer:
x > -1/3
Step-by-step explanation:
so first we are going to distribute the numbers outside of the parenthesis. which gives us the equation
18-9x-8+12x > 9
then we are going to add our like terms
so 12x + -9x gives us 3x
and 18 + -8 gives us 10
so it would gives us the equation 3x+10>9
we then subtract 10 from both sides to keep our numbers on the right which gives us
3x > -1
then we divide by 3 on both sides to get X
and we then get X > -1/3
always a positive number because it represents a distance from the mean.
3i √3
you can't have the square root of a negative number
so we use "i"
