Detailed explanation of x-cube-16x-x-cube + 9x + 3x square-27 + 5x

X cube - 16x-x cube + 9x + 3x square - 27 + 5x
=(1-1)x^3+3x^2+(-16+9+5)x-27
=3x^2-2x-27

Square of 9x - 2x + cube of 3x + (- 3x)

Original formula = 9x & # 178; - 2x + 3x & # 179; + 3x
=3x³+9x²-5x

The National Palace needs to paint four columns of the same length. The perimeter of the ground of each column is 3.14 meters and the height is 10 meters. How many square meters is the paint area of the four columns
Use the formula to solve the problem

3.14 * 10 * 4 = 125.6m2

Fill in appropriate operation symbols or brackets in each formula to make the equation hold. 5555 = 6,5555 = 3,5555 = 7555 = 8

I like this. 5-5 + 5 + 5 | 5 = 6; 5 * 5 + 5 = 30, 5 + 5 = 30, the ratio is 3
The third question is how to make 6 5S. I'll give you an answer: 5-5 + 5 = 5: (5 + 5) | 5 = 2;
5 + 5 = 10, (5 + 5 = 10) | 5 = 2, even if 8
If it's a five to seven, I'll give you an answer: 5|5 = 1, 5|5 = 1, the sum of two 1's and 5's is 7

Z = Xe ^ XY, find DZ

dz=(e^xy+xye^xy)dx+x^2e^xydy

If a, B are opposite to each other and C, D are reciprocal to each other, then what is 4 = of cube-3 (CD) of (a + b)

a. B is opposite to each other,
a+b = 0
c. D is reciprocal to each other
Then CD = 1
Then the cube of (a + b) - 3 (CD) is 4
=0-3
=-3

Four threes, just add, subtract, multiply, divide and brackets equal to 5

3+3-3÷3=5

The first-order functions y = (M-4) x + (1-m) and y = (M + 2) x + (2m-3) the image intersects the Y axis at two points a and B respectively. If point a and point B are symmetrical about the X axis, then the value of M is__

Let a point coordinate (0, y), B point coordinate (0, - y)
y=1-m——（1）
-y=（2m-3）——（2）
(1) (2) 1-m + 2m-3 = 0
m=2

The surface area of a large cuboid is 96 square meters. Cut it into small cubes of exactly the same size. What's the volume of each small cube?

"Xueer baby must win": first, turn this question upside down to say: two squares of the same size, the area after putting together a rectangle is 96 square meters. Find the volume of a small square? (96 square meters to 96 square centimeters, OK) put together a rectangle and reduce two faces, so that the area of each face is: 96cm ^ (6 × 2 -...)

7, 9, 11 and 12 are 24 points

(11-7)*9-12=24
