After the rain in Mao Mao, Miss Chun appeared with light steps in green gauze. She decorated the earth with green leaves and dazzling flowers. Miss Chun drove away the cold and created a vibrant scene.
You see the grass on the lawn is so withered and decayed in winter. Now I hear Miss Chun's call. They seem to wake up from a deep sleep and scramble to get their heads out of the ground, fearing that they will be the last one. The breeze blew, and the grass shook its head in the wind, as if thousands of little green hands were applauding to welcome Miss Chun. From a distance, it looks like a green blanket on the ground. Many nameless flowers adorn it, just like colorful gems, making the lawn more beautiful and attractive.
When it comes to the beauty of spring, of course, flowers are indispensable. Countless beautiful flowers bloom first in spring and compete for beauty. Look, the peach blossom is blooming brightly, the pink color is light yellow, and several green leaves set off the delicate petals, like a fairy in red. Wisteria is crawling all over the wall over there. The purple flowers on the wall are densely packed, hanging in strings like shy girls or purple waterfalls to welcome the spring girl.
There is also a spring breeze! The warm and soft spring breeze blows across the river, and the fish jump out of the water happily; Blowing through the valley, the valley was covered with green clothes; The wind blew across the fields, and crops began to sprout. Thousands of catkins in ..................................................................................................................................................................... were flying in the wind.
Beautiful spring, full of upgrade and hope, I will sing a hymn of spring with my heart!
Urgent! Mathematical Factorization in Senior Two [(x+p)+(x+q)][(x+p)-(x+q)]
=(x+p)^2-(x+q)^2
=x^2+2px+p^2-x^2-2qx-q^2
=2px+p^2-2qx-q^2
(x^2+y^2)(x^2-y^2)
=(x^2)^2-(y^2)^2
=x^4-y^4
(2x+y)^2-(x+2y)^2
=(2x+y-x-2y)(2x+y+x+2y)
=(x-y)(3x+3y)
=3(x-y)(x+y)
Does anyone know the price of Python full-stack training? Urgent! It seems that the front peak is around 1W8. At first, I was afraid that I couldn't learn. Coming here 1 month is not as difficult as I thought, and everything I said is easier to digest and absorb. Next, I will try to finish it in February after graduation.
On the addition and subtraction of quadratic roots in mathematics ~ ~ (9-a)/(3- root a)=(3+ root a)(3- root A)/(3-root a)=3+ root A.
The second problem is to calculate two consecutive integer ranges one by one and then add them.
7-4 root number 3=4+3-2 root number 12= (root number 4- root number 3) square =(2 root number 3) square is completely flat, and the other square root is root number 3-2.
(1 root 2- root 3)( 1 root 2+ root 3)=[ 1+ (root 2- root 3)][ 1- (root 2- root 3)]= 1.
Let's do the calculation again. This problem is the square difference formula.
Please add some points to the good answer. Thank you.
Two problems in primary school mathematics are kneeling. From A to B, uphill accounts for 2/7, flat road accounts for 4/7, and the rest are downhill. A car goes back and forth between A and B once, downhill for 42 kilometers. What is the distance between a and b?
Downhill: 1-4/7-2/7= 1/7.
The distance between Party A and Party B is 42÷ 1/7=294 (km).
How many kilograms of water does Xiao Wang need to add to dilute 150 kg of pesticide containing 20% liquid medicine into liquid medicine containing 5% liquid medicine?
Water:150x20% ÷ 5%-150 = 450 (kg)
To find the ratio, to write the process, you must use. If you want to step on it, the system will give you the answer within 2 minutes.
Simple solution equation (1)x+ 15%x=3.22 in grade five.
Solution: x+0. 15x=3.22, 1. 15x=3.22, so x=3.22/ 1. 15=2.8.
(2) 5.6÷70%x=5%
Solution: 5.6/0.7x=0.05, 0.7x = 5.6/0.05 =12, so x =112/0.7 =160.
(3) 75% of1.2 is 50% more than one number. Find this number.
Solution: Let this number be x, then there are equations: 1.2×0.75-x=0.5x, 1.5x=0.9, so x=0.9/ 1.5=0.6.
That is, this number is 0.6.
