Q. Select the expressions that are equivalent to 9t+9t9t + 9t.\newlineMulti-select Choices:\newline(A) 11t+3t+4t11t + 3t + 4t\newline(B) t×18t \times 18\newline(C) 7t+2t+9t7t + 2t + 9t\newline(D) 18t18t
  1. Simplify expression: Step 11: Simplify the given expression 9t+9t9t + 9t. Calculation: 9t+9t=18t9t + 9t = 18t.
  2. Compare to choices: Step 22: Compare the simplified expression to each choice.\newline(A) 11t+3t+4t=18t11t + 3t + 4t = 18t, matches 18t18t.\newline(B) t×18=18tt \times 18 = 18t, matches 18t18t.\newline(C) 7t+2t+9t=18t7t + 2t + 9t = 18t, matches 18t18t.\newline(D) 18t=18t18t = 18t, matches 18t18t.
