The tenths place is where the 5 is
To round, look at the number before it which is a 8
Since 8 is above 5 you round up
So the answer is 3,842.6
g(2) means plug in x = 2 into the function g(x) = |-2x + 4| and f(-1) means plug x = -1 into f(x) = 3x - 1.
That will give you two numbers that you can then use to calculate g(2) - f(-1)
Please see the picture below
Side = 8 - u / 2
28 = 2*2*7
Remove a pair of 2's:
√28 = 2√7
Well ur working with perimeter and its a square remember all sides will be the same so u would divde 250 and 125 from 4 so 250/4=62.5 and 125/4=31.25. so now u find that now hr taking away both of the perimeters cause ur finding how much GREATER so that will be 62.5-31.25= 31.25 if u have any more problems and if u have instagram my ne on it is j.j.henry.
