Write a cubic polynomial about the letter X, so that the polynomial contains the square of - 5x, and does not contain a linear term

The square of X & # 179; - 5x

The sum of a and B is 385. If the decimal point of a is moved one place to the right, it is equal to B. how many are a and B?
Very anxious! Very anxious! Very anxious!

A: 385 / (1 + 10) = 35
B: 385-35 = 350

On the quadratic equation 7x ^ 2 - (a + 13) x + 2A + 2 = 0 of X, there are two real numbers whose roots are between 0 and 1 and 1 and 2 respectively
On the quadratic equation 7x ^ 2 - (a + 13) x + 2A + 2 = 0 of X, there are two real numbers whose roots are between 0 and 1 and 1 and 2 respectively

First of all, we know that the function is open-ended upward. The root of the equation is not the intersection of the function and the X axis, that is, y = 0? But there should be two roots between 0.1 and 1.2, so the Y corresponding to 0 should be greater than 0, the Y corresponding to 1 should be less than 0, and the Y corresponding to 2 should be greater than 0

The number a is 100, the number B is 60 percent of the number a, and 4 percent of the number C is equal to the number B. the average of the three numbers is

A = 100 B = 100 * 60% = 60 C * 4 / 3 = 60 C = 45, so the average = (100 + 60 + 45) / 3 = 205 / 3

After several row elementary transformations, the augmented matrix B of AX = B of a system of non-homogeneous linear equations is
B=(2 -5 -4 2)
(0 1 1 -1/2)
(0 0 0 1)
Find R (a), R (b), judge the existence of the solution of this equation

R (a) = 2, R (b) = 3, because R (a) ≠ R (b), the equations have no solution

Both Party A and Party B have to process 360 parts. Party A processes 30 parts per hour and Party B processes 24 people per hour. How many hours does party a use less than Party B?

Party A: 360 / 30 = 12
Party B: 360 / 24 = 15
15-12=3
A uses 3 hours less than B

A rectangular iron block with length of 8 cm, width of 7 cm and height of 6 cm and a cube iron block with edge length of 5 cm are melted into a cylinder iron block with diameter of 20 cm, and the height of the cylinder iron block is calculated. (accurate to 0.01 cm)
There are 50 cars in team a and 41 cars in team B. how many cars should be transferred from team a to team B to make the number of cars in team B more than twice that of team a
A store sells a certain kind of clothing at the cost price of X Yuan. Now it increases the cost price by 30% and sells it with 20% discount. At this time, the actual price of each clothing is ()
It takes 4 days for Party A to complete a task alone and 8 days for Party B to complete it alone. Now party a works for 1 day first, and then completes the rest of the work together with Party B, then Party A makes a total of ()
For a job, it takes 10 days for Party A to complete it alone, 12 days for Party B to complete it alone, and 15 days for Party C to complete it alone?

Let the height of the cylinder be X
8*7*6+5*5*5=π.（20/2）²x
The solution is x = 1.47
Suppose x people are transferred from team a to team B
2（50-x）+1=41+x
The solution is x = 20
3. From the topic meaning: 0.8 * (1 + 30%) * x
Let a do a total of X days
x/4+（x-1）/8=1
The solution is x = 3
5. The solution needs X days to complete
2（1/10+1/15）+1/15+（1/12+1/15）x=1
The solution is x = 4
