1. Problem: Expand the algebraic expression $-3(-1 + 4e)$. 2. Formula: Use the distributive property $a(b + c) = ab + ac$. 3. Apply the distributive property: $$-3(-1 + 4e) = -3 \times (-1) + (-3) \times 4e$$ 4. Calculate each term: $$-3 \times (-1) = 3$$ $$-3 \times 4e = -12e$$ 5. Combine the terms: $$3 - 12e$$ 6. Final answer: $3 - 12e$ This process applies similarly to other parts, but only the first problem is solved as per instructions.
