L = lemon drops
J = jelly beans
L +J = 100
L=100-J
1.90L + 1.20J=1.48*100
1.90(100-j) +1.20J =148
190-1.90J+1.20J=148
190-0.7J=148
-0.7J=-42
J = 60
L=100-60 = 40
40 pounds of Lemon Drops are needed
Answer:
n²(n + 3)(n + 6)
Step-by-step explanation:
Take out a common factor of n² from each term
= n²(n² + 9n + 18) ← factorise the quadratic
= n²(n + 3)(n + 6)
