Can somebody solve this: x^4+2x^3-25x^2-26x+120

Answers

Answer:

(x + 5) • (x + 3) • (x - 2) • (x - 4)

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 1 • 15 = 15

Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .

-15 + -1 = -16

-5 + -3 = -8

-3 + -5 = -8

-1 + -15 = -16

1 + 15 = 16

3 + 5 = 8 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5

x2 + 3x + 5x + 15

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x+3)

Add up the last 2 terms, pulling out common factors :

5 • (x+3)

Step-5 : Add up the four terms of step 4 :

(x+5) • (x+3)

Which is the desired factorization

(x + 5) • (x + 3) • (x - 2) • (x - 4)

Task 10: It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate:

How many pounds of mashed potatoes can they make with 15 pounds of potatoes?

Answers

Answer:

The answer is 22.5 lbs or 22 and a half lbs of mashed potatoes.

Step-by-step explanation:

The ratio of potatoes is 1.5.

10 lbs potatoes * 1.5 = 15 lbs mashed

So 15 lbs potatoes * 1.5 is: 22.5 lbs mashed potatoes.

The admission ticket for Pat Pat Zoo is $1.50 for children and $4.00 for adults. On a certain day, 2200 people went to the zoo and $5050 was collected. How many children and how many adults went to the zoo that day?

Answers

Answer:

1380 children and 820 adults went to the zoo that day

Step-by-step explanation:

System of Equations

Define the following variables

x = number of children that went to the zoo

y = number of adults that went to the zoo

On a certain day, 2000 people went to the zoo, thus:

x + y = 2000

Solving for x:

x = 2000 - y [1]

The admission ticket is $1.50 for children and $4.00 for adults and that same day, $5050 was collected, then:

1.50x + 4y = 5050 [2]

Substituting x from [1]:

1.50(2000 - y) + 4y = 5050

Operating:

3000 - 1.50y + 4y = 5050

3000 + 2.5y = 5050

Subtracting 3000

2.5y = 5050 - 3000 = 2050

Dividing by 2.5

y = 820

From [1]

x = 2200 - 820 = 1380

1380 children and 820 adults went to the zoo that day

Measurement of 5 quarts is equal to 20 cups.

What are Measurements?

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

We have the measurement, 1 cup = 1/4 quarts

Let x be the number of quarts for 20 cups.

By using proportion,

1 / (1/4) = 20 / x

Cross multiplying,

x = 20 × (1/4)

x = 5

Hence the measurement of 20 cups is equal to 5 quarts.

Thee measurement equals to 20 cups is 5 quarts.

Thus, option (a) is correct.

To determine which measurement is equal to 20 cups, compare the conversion factors between cups and each of the given measurements.

As, the conversion factors are:

1 quart is equal to 4 cups 1 pint is equal to 2 cups 1 gallon is equal to 16 cups 1 fluid ounce is equal to 0.125 cups

1. 5 quarts

= 5 x 4 cups/quart

= 20 cups

2. 40 pints

= 40 x 2 cups/pint

= 80 cups

3. 1 gallon

= 1 x 16 cups/gallon

= 16 cups

4. 320 fluid ounces

= 320 x 0.125 cups/fluid ounce

Use the elimination method to solve the following system of equations:
2x+y=3
3x – y= 12
The solution is

Answers

x = 3

y = -3

(3, -3)

Step-by-step explanation:

Choose one of the equations and isolate y. I will use the first one.

2x + y = 3

Y = 3 - 2x

Now sub the solution for y into the equation below.

3x - y = 3

3x - (3 - 2x) = 12

3x - 3 + 2x = 12

5x - 3 = 12

5x = 15

x = 3

To get y, sub the answer for x into one of the equations.

2(3) + y = 3

6 + y = 3

y = 3 - 6

y = -3

Answer:

(x,)y) =(3,-3)

Step-by-step explanation:

add the equations vertically to eliminate one variable

2x +y = 3

3x -y = 12

5x =15 divide both sides by 5

x = 3 now substitute the given value of x into the equation 2x+y=3

2 x 3 + y = 3 multiply 2x3

6 +y =3 move constant to the right

y = 3-6

y = -3
