Answer:
-9n
Step-by-step explanation:
3n(5 + 3n - 8 - 3n)
First we combine the like terms inside the parenthesis:
3n(-3)
Because 5 -8 = -3 and 3n - 3n = 0
Now we multiply:
-9n
because 3n × -3 = - 9n
So the answer is -9n

Answer: 21/400
Step-by-step explanation:
Multivitamin:
8 cherry, 5 grape, and 7 orange
Total fruits in Multivitamin container :
(8 + 5 + 7) = 20
P(orange) = Total required outcome / Total possible outcomes)
P(orange) = 7/20
Calcium vitamin :
11 berry, 3 lemon, and 6 pineapple
Total fruits in calcium vitamin container:
(11 + 3 + 6) = 20
Probability of picking a lemon:
P(lemon) = Total required outcome / Total possible outcomes)
P(lemon) = 3/20
Therefore, probability of picking an orange and a lemon equals:
P(orange) × p(lemon) = (7/20) × (3/20) = 21/400
