Q. Which expression is equivalent to 4(b+5)4(b + 5)?\newlineChoices:\newline(A) 4b+204b + 20\newline(B) 20b+420b + 4\newline(C) 9b9b\newline(D) 20b20b
  1. Distribute 44: Distribute the 44 across the terms inside the parentheses.\newline4(b+5)=4×b+4×54(b + 5) = 4 \times b + 4 \times 5
  2. Perform multiplication: Perform the multiplication.\newline4×b=4b4 \times b = 4b\newline4×5=204 \times 5 = 20\newlineSo, 4(b+5)=4b+204(b + 5) = 4b + 20
