Answer:
x = ±2
Step-by-step explanation:
3x ^2 -4 = 8
Add 4 to each side
3x ^2 -4+4 = 8+4
3x^2 =12
Divide each side by 3
3x^2 =12
3x^2/3 = 12/3
x^2 = 4
Take the square root of each side
sqrt(x^2) = ±sqrt(4)
x = ±2
Whenever you have the answers for TOTAL MILES RUN and HOW MANY HOURS RUN (which you do), just divide the total miles by the amount of hours!
So, do 231 / 10.5
This is equal to 22!
( 2a2 - 2b - 1 ) Is the answer when simplifying the expression.
I believe the answer would be (1) because they are not directly related
