It is known that a is a prime number, and a+6, a+8, a+12, and a+14 are all prime numbers; Try to find all the prime numbers a that meet the requirements. 【a=5】

1 Tang Liu Yuxi Lake Junshan Huli : Stone.

To do this kind of problem is to find multiple equations, and then find the unknowns.

Because A has the correct solution, he brings x=1 y=-1 into the system of equations ax+by=2 cx-3y=-2

We get a+b=2, c+3=-2, so c=-5

Because B copied the wrong c, the solution is x=2 y=-6, so x=2 y=-6 can be brought into ax+by=2 to get 2a-6b=2, and a=b=2 is combined to get a=7 4, b=1 4

So a=7 4, b=1 4, c=-5

Bringing x=1 into x2+px+q gives 1+p+q=0, and bringing x=-2 into x2+px+q gives 4-2p+q=5

Solve the two equations of 1+p+q=0, 4-2p+q=5 to obtain p=-2 3, q=-1 3

1。There is a circular lawn with a circumference of meters, and it is ready to be equipped with an automatic rotary sprinkler irrigation device, and there are three kinds of devices with a range of 20 meters, 10 meters, and 15 meters, which one do you think is more appropriate? Where is it installed?

Choose a 10-meter one, because the diameter is 20 and the radius is 10, and it's installed in the center of the circle. ）

This poem is written that Li Ping's playing of Konghou is very beautiful, and the rhetoric is gorgeous and beautiful, which makes people look at it as if they are in the scene, as if the beautiful music is next to their ears.

Qinyuan Spring Snow is just a young classmate, in the prime of life, pointing to the passionate words, the dung was ten thousand households in the year!

Math problem is for elementary school students, just tell you method 1, calculate the radius of the circle, then calculate the area of the circle, and then use the radius to calculate the area of the circle to see which is closest to the area of the previous circle (and at least the area of the rain circle).

2. Subtract the area of the minor circle from the area of the large circle.

3. Calculate the surface area of the wheel except for two circles, so that you can know the distance traveled by the car in 20 minutes, and walk 160 weeks in 20 minutes.

If you don't use pen and ink, you don't read.

1.The words "grams" and "actually" should be crossed out

2.(Regardably) it is a newspaper, a magazine, a **, or a short, medium, or long story, as long as you can find it, you can read it.

3.Fee: Flowers, use. Light: Single, only.

4.In addition, you should also develop the habit of taking reading notes, you can make excerpts, memorize summaries, but also write down your experience and experience, which is what I often say if you don't use pen and ink and don't read.

6."Write more" is the foundation of a good essay. Some good sentences and paragraphs, just reading and thinking are not enough, they must be written down.

It is necessary to make excerpts, memorize experiences, and write down experiences. Learning knowledge is a process of accumulation, and only by "using pen and ink" can we improve the level of writing.

I advise you to use your time on the Internet to go to the bookstore to buy a volume and make it yourself, if you are reluctant to spend a few dollars, go to the relevant ** to see.

4 = 3 (decimeter) 3 3 = 9 (square decimeter) 12 4 + 9 = 57 (square decimeter).

A: To make this pair of buckets, you need at least 57 square decimeters of iron sheet.

12 4 = 3 (decimeters) 3 3 4 = 36 (liters) Answer: The volume of this bucket is a total of 36 liters.

4/4 = 3/8 = 1/2 = 2/3 = Cycle 4/5 = 7/9 = Cycle 5/6 = Cycle.

Base length = 12 4 = 3 dm.

Iron sheet = 3 3 + 12 4 = 57 square decimeters.

Volume = 3 3 4 = 36 liters.

1.Side length of the bottom surface: 12 4=3 dm.

At least iron sheets are required: 3 3 + 3 4 4 = 57 square decimeter volume: 3 3 4 = 36 l

Base length = 12 4 = 3 dm.

Iron sheet = 3 3 + 12 4 = 57 square decimeters.

Volume = 3 3 4 = 36 liters.

3 8<1 2<4 7<2 3<7 9<4 5<5 6 Give a point Thank you in advance.

1 Square side length = 12 divided by 4 = 3 Base area = 3 times 3 = 9 square decimeters, side area = 3 times 4 times 4 = 48 square decimeters.

48 + 9 = 57 square decimeters.

Volume = 3 3 4 = 36 liters.

Side length: 12 4 = 3 dm.

Surface area: 3 4 2 + 3 4 2 + 3 3 = 57 dm Volume: 3 3 4 = 36 liters.

Requires Iron Sheet 6|+48 square decimeters.

Bucket volume 24|cubic decimeters.

Three-eighths One-half Four-sevenths two-thirds Sevenths Four-fifths Five-sixths.

Iron sheet area: 3 times 3 plus 12 times 4 equals 57 square decimeters.

Volume: 12 times 4 equals 36 square decimeters.

Sort: 3/8 1 2 4 7 2 2 3 7 7 7 7 7 5 5 5 5

1) Bottom side length: 12 4=3

The bottom area is 3*3=9

The area of 4 sides: 3*4*4=48

The amount of iron sheet needed for a bucket: 9 + 48 = 57

The iron sheet required for two buckets: 57 * 2 = 114, the unit is square decimeter, and the volume of one bucket is: 3 * 3 * 4 = 36

The volume of two buckets is: 36 * 2 = 72 (square decimeters) = 72 liters 2) 3/8< 1/2< 4/7< 2/3< 7/9< 4/5< 5/6

1.Solution: From the meaning of the question, it can be seen that the side length of the bottom edge is 3 cm, and the high edge is 4 cm, so the surface area is (3*4*4+3*3)*2=114 (square decimeters).

The volume is: 3 * 3 * 4 * 2 = 72 (cubic decimeters) Don't forget that it is a pair of cylinders Answer: to make this pair of barrels, at least 114 square decimeters of iron sheet should be used, and the volume of this pair of buckets is a total of 72 cubic decimeters.

2.The first pass is 3 8<1 2<4 7<2 3<7 9<4 5<5 6

Base length = 12 4 = 3 dm.

Iron sheet = 3 3 + 12 4 = 57 square decimeters.

Volume = 3 3 4 = 36 liters.

As it is a pair, iron sheet = 57 2 = 114 square decimeter volume = 36 2 = 72 liters.

Iron sheets 114 square decimeters, 72 liters of water, 3/8, 4/7, 1/2, 2/2, 2/3, 5/6, 7/9, 4/5

1: Iron sheet: one (12 divided by 4) x 4 x 4 + (12 divided by 4) x (12 divided by 4) = 57 (square decimeter) pair: 57x2 = 114 (square decimeter) Volume: (12 divided by 4) x (12 divided by 4) x 4x2 = 72 (liters).

2: 3/8 1/2 3/7 2/3 7/9 4/5 5/6.

1 question. The (without lid) surface area of the cuboid bucket is s=l*h, where l is the circumference of the bottom surface and h is the height. Volume v = base area * height.

It's the meaning of multiplication).

From the inscription, the bottom side length is 3, and the height is 4.

So s=12*4=48 square decimeters v=3*3*4=36 cubic decimeters.

2 questions. From small to large: 3/8< 1/2< 4/7< 2/3< 7/9< 4/5< 5/6

1. 3*3+4*3*4=57*2=114. 2*3*3*4=48

2.3/8 1/2 4/7 7 7/7 4/5 5/6

(12 4) 2 + 4 * 3 * 4 = 57 square decimeters.

12 4) 2*4=36 cubic decimeters.

First of all, the area of this land is.

9kg per square meter, then a total of 138x9=1242kg
