Answer asap, i'm on the clock, !
part d
three students evaluated three different expressions using the real number properties and the order of operations. answer each question based on the processes they used and their results.
student 1: 5 - 2(4 + 9) - 11
5 - 2(4) - 2(9) -11
5 - 8 - 18 -11
5 + (-8) + (-18) + (-11)
-3 + (-18) + (-11)
-21 + (-11)
-32
student 2: -9 + (6 + 9) - 42
-9 + (9 + 6) - 42
(-9 + 9) + 6 - 42
0 + 6 - 42
0 + 6 - 16
0 + 6 + (-16)
6 + (-16)
-10
student 3: -4(14) - 32 - 2 ∙ 0
-4(10 + 4) - 32 - 2 ∙ 0
-4(10) - 4(4) - 32 - 2 ∙ 0
-40 - 16 - 32 - 2 ∙ 0
-40 - 16 - 9 - 2 ∙ 0
-56 - 9 - 2 ∙ 0
-65 - 2 ∙ 0
-67 ∙ 0
0
