Which of the following expressions is not equivalent to 5a+30? show and explain your work! you! a. 2a+a-2+2a+32 b. (5a x 2) + (5 x 30) c. 6a+15-a+15

yes yes yes yes yes yes yes yes yes

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

step-by-step explanation:

what do you mean by "representation"? graph? table? etc.

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:
