Determine

Simplify: x(v+x) x* O A (y+x) B (y+1) C (v+1) O D (y+x)

Let a=⟨−2,3,4⟩, b=⟨4,5,−2⟩, and c=⟨2,0,1⟩. Determine [(a×b)×c]−[a×(b×c)]. Hint: Try to simplify the expression first to make the calculations easier! Select one: a. ⟨20,−10,−16⟩ b. ⟨12,13,6⟩ c. ⟨24,−5,−18⟩ d. ⟨12,−18,−24⟩ e. ⟨10,−18,−25⟩

2 The expression (x – 5)(x² + 3x + 4) equals Ax + Bæ? + - where A equals: and B equals: and C equals: and D equals:
