Q. Select the expressions that are equivalent to 5q+2q5q + 2q.\newlineMulti-select Choices:\newline(A) q+4q+2qq + 4q + 2q\newline(B) q7q^7\newline(C) q×7q \times 7\newline(D) 6q6q
  1. Simplify expression: Step 11: Simplify the expression 5q+2q5q + 2q.\newlineCalculation: 5q+2q=7q5q + 2q = 7q.
  2. Compare with choices: Step 22: Compare the simplified expression with each choice.\newline(A) q+4q+2q=7qq + 4q + 2q = 7q, matches 7q7q.\newline(B) q7q^7, does not match 7q7q.\newline(C) q×7=7qq \times 7 = 7q, matches 7q7q.\newline(D) 6q6q, does not match 7q7q.
