Which of these is the same as 3,068
a. (30×1,000)+( 68×1)
b. (6×10)+(8×1)

3,608 = 3*1000 + 0*100 + 6*10 + 8*1

or

3,608 = 3*1000 + 6*10 + 8*1

It seems like neither answer choice shows this. So perhaps there's a typo somewhere?

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
