Anybody plz will give brainliest and lots of points

what is the mean absolute deviation of the data set?

{2, 8, 10, 12}

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
