12. It takes James 20 minutes to ride his bike to the lake by one path, and 30 minutes to come back by a different path. If he goes to the lake and
back 4 times, how many minutes does he spend riding? Which gives the
answer? *
O (8+20) x (8+30) = 28 x 38 = 1,064 minutes
О
8 x 20 x 30 = 4,800 minutes
О
(8+8) X (20+30) = 16 x 50 = 800 minutes
O (8x20) + (8x30) = 160 + 240 = 400 minutes

it is b)

hope this : )

step-by-step explanation:

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
