2x - 7 = 2x - 14
2x = 2x - 7.
Matt is incorrect, there are actually 0 correct answers to this equation.
Answer:
a) 8 x 10^3 or 8000
b) 8 x 10^-2 or .08
Explanation: Refer to a guide on rounding sig figs
Based on your answer where ask to determined the number of outcome and decide whether the event is simple or not.
-So in event A is 4000 and a sample space
-So event B is 500 its just a number of outcome
Substitute the given number into the equation
Sum = 180(15-2)
Solve brackets
180(13)
Which is equal to 2340
So, the sum of interior angles is 2340 degrees
13 because you do 18-8 and you get 10 and divide that by 2 and you get 5 then add 5 to 8 and you get 13 and subtract 5 from 18 and you get 13 as well. Hope that helps
