What is the factored form of 2x3 + 4x2 – x?a) 2x ( x^2 + 2x + 1)
b) x (2x^2 + 4x + 1)
c) 2x (x^2 + 2x - 1)
d) x (2x^2 + 4x -1)

Answers

Answer 1
Answer: To solve this question, we need to write this equation in simplified form.
So, Taking the GCF from 2x³ + 4x² - x,  
x is divisible by all of them so our new equation will be,

x ( 2x² + 4x - 1)
Correct option is D.

Hope this helped you.. :)

When ordering a sundae, you may choose three toppings from their list of 10 available. Assuming that your chosen toppings must be different, how many different sundaes with three toppings can you order?

Answers

Answer:

there are 120 different sundaes with three toppings you can order.

Step-by-step explanation:

If the chosen toppings must be different, then that means it's a Combination where the order doesn't matter (as long as they're all different).

Equation: 10C3

Forming Equation: 10!/(10-3)!*3!=10*9*8*7!/7!*3!=10*9*8/6=720/6=120

Therefore, there are 120 different sundaes with three toppings you can order.

¿Cuántos litros de agua se precisa para llenar una piscina inflable de 1/4 de metro cúbico?

Answers

Answer:

250 litters

Step-by-step explanation:

To solve this question, we first need to know the conversion from cubic meter to liter.

1 cubic meter is equal to 1000 liters.

So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:

1 m3 -> 1000 L

1/4 m3 -> x L

x * 1 = (1/4) * 1000

x = 1000 / 4 = 250 L

So we need 250 liters of water.

Which of these is an example of discrete data?A. Rides in an amusement park
B. Temperature
C. Distance
D. Area of a room

Answers

Discrete data is numerical but only has a limited number of values.

In this case, the number of rides in an amusement park would be discrete because you cannot have, for example, 5.6 rides.

The correct answer is A.

Solve the system of equations. 2x − 5y = 3
x − 3y = 1
(4, 1)
(5, 2)
(7, 2)
(9, 3)

Answers

Answer: First Option is correct.

Step-by-step explanation:

Since we have given that

2x-5y = 3\n\n x -3y = 1

Now, we will use "Substitution Method" to find the values of x and y:

x=1+3y\ -(3)

Put the value of x in first equation i.e.

2x-5y = 3

2(1+3y)-5y=3\n\n2+6y-5y=3\n\n2+y=3\n\ny=3-2\n\ny=1

Now, we use the value of y in equation (3),

x=1+3y\n\nx=1+3*1\n\nx=1+3\n\nx=4

Hence, values of (x,y) is (4,1).

Therefore, First Option is correct.
2x - 5y = 3
x - 3y = 1...multiply by -2
---------------
2x - 5y = 3
-2x + 6y = -2 (result of multiplying by -2)
--------------add
y = 1

x - 3y = 1
x - 3(1) = 1
x - 3 = 1
x = 1 + 3
x = 4

solution is (4,1)
