QuestionFind expressions equivalent to 2(s+9)2(s+9). Options: 2s+182s+18, (s+9)2(s+9)2, 18s+218s+2, 11s11s.

Studdy Solution
Now, we compare the simplified expression 2s+182s +18 with the given options.
Option1 2s+182s +18 is equivalent to the simplified expression.
Option2 (s+9)2(s+9)2 is equivalent to the given expression 2(s+9)2(s+9), because multiplication is commutative, i.e., ab=baab = ba.
Option3 18s+218s +2 is not equivalent to the simplified expression, because the coefficients of ss and the constant term are not the same.
Option4 11s11s is not equivalent to the simplified expression, because it lacks the constant term 1818.
Therefore, the expressions equivalent to 2(s+9)2(s+9) are 2s+182s +18 and (s+9)2(s+9)2.
