Answer:
aw ty but is there a question?
Step-by-step explanation:
If (x+2) is a factor of 3x^2+14x+k, the equation must equal zero when x=-2 so:
3(-2)^2+14(-2)+k=0
12-28+k=0
-16+k=0
k=16
Let the first number be x
The second number is x + 2
The third number is x + 4
x + x + 2 + x + 4 = 270
3x = 270 - 6
x = 88
x is not prime so there is no first number!
Answer:
Step-by-step explanation:
combo 1 : 3 cheese and 1 pepperoni
combo 2: 2 cheese and 2 pepperoni
combo 3: 1 cheese and 3 pepperoni
he chooses :
5 combo 1's : so thats (5 * 3) = 15 cheese, (5 * 1) = 5 pepperoni
2 combo 2's.....(2*2) = 4 cheese and (2 * 2) = 4 pepperoni
3 combo 3's....3(3 * 1) = 3 cheese and (3 * 3) = 9 pepperoni
added = a total of 22 cheese and 18 pepperoni....thats 40 pizzas
so the probability that he will randomly pick a pepperoni is 18/40 which reduces to 9/20
the probability that he will pick a cheese is 22/40 which reduces to 11/20
so ur answer is D. <===
