5x^3+15x^2+10x please help with this I need to see how its worked out not just the answer I no the answer just don't no how to work out the problem
Answers
5x^3+15x^2+10x = 0
x(5x^2+15x+10) = 0
=> x=0
5x^2+15x+10=0
5(x^2+3x+2)=0
=> (x+1) (x+2) = 0
x= -1 , x= -2
it has three answers, hope im right :)

Answers
Here is how you solve the question:
1. Write the question out as a fraction.
2. Since percent means, 'Out of 100', get 100 as the denominator.
So, the answer is 360 cookies.

Answer:
20 ways
Step-by-step explanation:
6C3 = 6!/(3! * (6-3)!)
= (6*5*4*3*2*1)/(3*2*1*(3)!)
= (6*5*4) / (3 * 2 * 1)
= (6*5*4)/6
= 5 *4
= 20 ways
Final answer:
The number of ways to pick 3 items not to take out of a total of 6 is 20.
Explanation:
To find the number of ways to pick 3 items not to take out of a total of 6, we can use the combination formula. The formula for combinations is given by C(n, r) = n! / (r!(n-r)!), where n is the total number of items and r is the number of items to be chosen. In this case, n = 6 and r = 3. Plugging in these values, we get:
C(6, 3) = 6! / (3!(6-3)!) = 6! / (3!3!) = (6 * 5 * 4) / (3 * 2 * 1) = 20.
So, there are 20 different ways to pick 3 items not to take out of a total of 6.

The values are:
- for the black chip : x₁ = 2
- for the red chip: x₂ = -1
Let's first calculate the possibilities of each chip. There are in total 5 chips (two black chips and three red chips) in the bag
- the possibility to draw the black chip is 2 out of 5: P₁ = 2/5
- the possibility to draw the red chip is 3 out of 5: P₂ = 3/5
In this example we have 4 different events:
1. Drawing of two black chips: P₃ = P₁ · P₁ = 2/5 · 2/5 = 4/25
2. Drawing of one black chip and then one red chip: P₄ = P₁ · P₂ = 2/5 · 3/5 = 6/25
3. Drawing of one red chip and then one black chip: P₅ = P₂ · P₁ = 3/5 · 2/5 = 6/25
5. Drawing of two black chips: P₆ = P₂ · P₂ = 3/5 · 3/5 = 9/25
Therefore, the expected value for each round if there are two draws per round and the chips are replaced after each draw is 0.4:
P = (x₁ + x₁) · P₃ + (x₁ + x₂) · P₄ + (x₁ + x₂) · P₅ + (x₂ + x₂) · P₆
P = (2+2) · 4/25 + (2-1) · 6/25 + (2-1) · 6/25 + (-1 + -1) · 9/25
P = 4 · 4/25 + 1 · 6/25 + 1 · 6/25 + -2 · 9/25
P = 16/25 + 6/25 + 6/25 - 18/25
P = 28/25 - 18/25
P = 10/25 = 0.4
Answer:
0.4 is correct

Final answer:
The liters of milk remaining in the tank after leaking for t weeks is represented by an exponential function. An exponential function is a mathematical function in which the independent variable appears as an exponent.
Explanation:
The function that represents the liters of milk remaining in the tank after leaking for t weeks is an exponential function. An exponential function is a mathematical function in which the independent variable appears as an exponent. In this case, the liters of milk lost each week is constant, so the amount of milk remaining in the tank is decreasing exponentially over time.
Formula for exponential decay: M = P * (1 - r)^t, where M is the amount of milk remaining, P is the initial amount of milk, r is the rate of decay, and t is the number of weeks.
In this case, the initial amount of milk, P, is 600 liters and the rate of decay, r, is 60/600 = 0.1 (10%). So the exponential function that represents the liters of milk remaining after t weeks is M = 600 * (1 - 0.1)^t.
