Q. Which expression is equivalent to 5(m+9)5(m + 9)?\newlineChoices:\newline(A) 5m+455m + 45\newline(B) 14m14m\newline(C) 45m45m\newline(D) 45m+545m + 5
  1. Distribute 55 to m and 99: Distribute the 55 to both m and 99.\newline5(m+9)=5⋅m+5⋅95(m + 9) = 5\cdot m + 5\cdot 9
  2. Multiply 55 by mm and 99: Multiply 55 by mm and 55 by 99.
    5×m=5m5\times m = 5m
    5×9=455\times 9 = 45
    So, 5(m+9)=5m+455(m + 9) = 5m + 45
