Spencer multiplies 3540×8 he gets his answer using the strategy shown 3000×8+500×8+4×8 = 2000 28,032 which statement explains whenever Spencer's answer is correct

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.

step-by-step explanation:

27 +27 or 27times 2=54

the diffrence is 0
