Q. Which expressions are equivalent to 4d+6+2d 4 d+6+2 d ?\newlineChoose all answers that apply:\newline(A) 2(3d+3) 2(3 d+3) \newline(B) 6(d+6) 6(d+6) \newline(C) (3d+3)+(3d+3) (3 d+3)+(3 d+3)
  1. Simplify Expression: First, we need to simplify the given expression by combining like terms.\newline4d+6+2d4d + 6 + 2d can be simplified by adding the 'd' terms together.\newline4d+2d=6d4d + 2d = 6d\newlineSo the simplified expression is 6d+66d + 6.
  2. Check Option A: Now let's check each answer choice to see if it is equivalent to the simplified expression 6d+66d + 6.\newlineOption A: 2(3d+3)2(3d+3)\newlineWe distribute the 22 into the parentheses.\newline2×3d=6d2 \times 3d = 6d\newline2×3=62 \times 3 = 6\newlineSo, 2(3d+3)2(3d+3) simplifies to 6d+66d + 6.
  3. Check Option B: Option B: 6(d+6)6(d+6)\newlineWe distribute the 66 into the parentheses.\newline6×d=6d6 \times d = 6d\newline6×6=366 \times 6 = 36\newlineSo, 6(d+6)6(d+6) simplifies to 6d+366d + 36, which is not equivalent to 6d+66d + 6.
  4. Check Option C: Option C: 3d+3)+(3d+3)(3d+3)+(3d+3)(\newlineWe combine like terms.\newline\$3d + 3d = 6d\)\(\newline\)\(3 + 3 = 6\)\(\newline\)So, \(3d+3)+(3d+3)\ simplifies to \$6d + 6\).
