I've been having trouble with these four problems. Please help.
1)-8n(6 - 7n) + 2(3n - 8)
2)-3k(-8k - 6) - 5(-8k + 8)
3) -5a(a - 1) - (4a + 8)
4)-4(b - 3) - 8(b - 2)
Use Distributive Property.
a(b+c) = ab + ac
1)-8n(6 - 7n) + 2(3n - 8)
2)-3k(-8k - 6) - 5(-8k + 8)
3) -5a(a - 1) - (4a + 8)
4)-4(b - 3) - 8(b - 2)
a(b+c) = ab + ac
