I'm sorry, I'm not very good at mathematics. What's your age

I hope I can write down some math problems together with the formula
1. The edge length of a cube is 10 decimeters. If the cube is cut into small cubes with an edge length of 2.5 decimeters, you can cut () cubes. The sum of the surface areas of these small cubes is () square decimeters
2. Fill in greater than or equal to
885 of 888 □ 55 of 58151 of 30049 of 102

The edge length of a cube is 10 decimeters. If the cube is cut into small cubes with an edge length of 2.5 decimeters, it can be cut into (64). The sum of the surface areas of these small cubes is (2400) square decimeters
10*10*10/(2.5*2.5)=64
2.5*2.5*6*64=2400
2. Fill in greater than or equal to
885 out of 888 > 55 out of 58 > 151 out of 300 > 49 out of 102

A mathematical problem, hope to have formula and results, to the right
The average monthly income of Zhang Li's father was 720 yuan in 1993, 980 yuan in 1997 and 1280 yuan in 2003. How much did the average monthly income of Zhang Li's father in 2003 increase compared with that in 1993? How much did it increase compared with that in 1997
The output of rapeseed this year is 14% higher than that of last year, that is, the output of this year is% higher than that of last year, and the output of this year is% higher than that of last year
3. Deposit 10000 yuan in the bank at the monthly interest rate of 0.14% for 3 months, and pay 20% of the interest after maturity according to the regulations
It takes four hours for a to finish the same job, and five hours for B. how much higher is the efficiency of home work than that of B
A. (1 / 5-1 / 4) / 1 / 5 * 100%
B. (1 / 4-1 / 5) / 1 / 5 * 100%
C.（5-4）/5*100%
D. (1 / 4-1 / 5) / 1 / 4 * 100%

The average monthly income of Zhang Li's father was 720 yuan in 1993, 980 yuan in 1997 and 1280 yuan in 2003. How much did the average monthly income of Zhang Li's father in 2003 increase compared with that in 1993? How much did it increase compared with that in 1997
（1280-720）/720=77.8%
（1280-980）/980=30.6%
A: the average monthly income in 2003 was 77.8% higher than that in 1993 and 30.6% higher than that in 1997
The output of rapeseed this year is 14% higher than that of last year, that is, the output of rapeseed this year is 14% higher than that of last year, and the output of rapeseed this year is 114% higher than that of last year
(14% equals 14%)
3. Deposit 10000 yuan in the bank at the monthly interest rate of 0.14% for 3 months, and pay 20% interest and 10033.6 yuan after maturity?
10000*0.14%*3*（1-20%）+10000=10033.6

B
A. (1 / 5-1 / 4) / 1 / 5 * 100%
B. (1 / 4-1 / 5) / 1 / 5 * 100%
C.（5-4）/5*100%
D. (1 / 4-1 / 5) / 1 / 4 * 100%

Discriminant of quadratic equation with x-ax + 1 = 0.1 variables

b²-4ac

Using the discriminant of quadratic equation, we get [2 (α, β)] & sup2; - 4 (β, β) (α, α)

For example, if the quadratic equation is ax ^ 2 + BX + C = 0, we can get x ^ 2 + (B / a) x + (C / a) = 0, and then we can get [x + (B / 2a)] ^ A + [(C / a) - (b ^ 2 / 4A ^ 2] = 0. If we want to have a solution, then [(C / a) - (b ^ 2 / 4A ^ 2] = 0. This is the process of the origin of the discriminant of quadratic equation

The equation 3x2-6x-1 = 0 is reduced to (x + m) 2 = K in the form of______ ．

3x2-6x-1 = 0, 3x2-6x = 1, x2-2x = 13, x2-2x + 1 = 13 + 1, (x-1) 2 = 43, so the answer is: (x-1) 2 = 43

The quadratic equation of one variable (x + 3) & sup2; = x (3x-1) is reduced to a general form
ditto
It's quadratic first, then it's quadratic, then it's a constant, and finally it's going to be equal to 0

2x^2-7x-9=0

The quadratic equation of one variable (x + 3) = x (3x-1) is changed into a general form（
fast

3x^2-2x-3=0

(2-x) (3x + 4) = 3 becomes the general solution of quadratic equation with one variable

(2-x)(3x+4)=3
6x+8-3x²-4x=3
2x-3x²+8=3
3x²-2x-5=0

The equation (3x = 1) & # - 6x = 2 is reduced to the general form as () the coefficient of quadratic term is () the coefficient of primary term is () the constant term is ()

（3x+1）²-6x=2
9x²+6x+1-6x-2=0
9x²-1=0
The coefficient of quadratic term is (9), the coefficient of primary term is (0), and the constant term is (- 1)
