Summary. Comprehensive application solution: spelling one:

12 small squares in 1 row Spell 2: 12 small squares in 2 rows of 6 columns; Spell 3: 12 small squares arranged in 3 rows and 4 columns; So with 12 small squares with a side length of 1 cm, you can put together 3 different rectangles.

Hello, please help me take a look.

Hello. Could you please help me take a look, a capability improvement, a comprehensive application.

Figure: You can help me draw it simply.

Can I send one without a watermark?

The child sent it to me.

I don't think she will.

Use 12 small squares with the same length to spell out different rectangles, please draw them.

Ability improvement: 1 question: 32 questions: rectangular 3 2

In the picture on the right, the largest square is cut off, and the side length is how many centimeters.

What is the shape of the picture, how many centimeters long, and how many centimeters wide is in the rest of the picture.

The picture is a rectangle.

Comprehensive application solution: Spelling 1: 12 small squares arranged in 1 line Spelling 2:

12 small squares in 2 rows and 6 columns; Spell 3: 12 small squares arranged in 3 rows and 4 columns; So with 12 small squares with a side length of 1 cm, you can put together 3 different rectangles.

This is a type of orchid - spider plant, which has a high ornamental value. Spider plant is also known as: weeping pot grass, hanging orchid, fishing orchid, orchid grass, folding crane orchid, Western Europe is also called spider grass or aircraft grass, native to South Africa.

Monocots, liliaceae, and spider plants are perennial evergreen herbaceous plants with rhizomes that are flat or oblique, and have mostly thick roots. The leaves are clustered, linear, and the leaves are slender, like orchids. Sometimes there are green or yellow stripes in the middle.

The flower stems are drawn from the leaf clusters, growing into stolons, and the leaves are drawn in clusters at the apex, the flowers are white, often 2-4 flowers are clustered, arranged in scattered racemes or panicles, and occasionally purple petals appear inside; Capsule triangular oblate spherical, about 5 mm long and 8 mm wide, with 3-5 seeds per chamber. The flowering period is May, and the fruiting period is August. The plant has the effect of purifying the air, and the whole plant can be used as medicine.

At present, the flower market of spider plant is about 100-800 yuan per pot of finished products, of course, the price will increase greatly when you go to the orchid appreciation meeting.

It is a kind of orchid, and there are thousands of species of orchids.

Orchids shouldn't have much money, just more than ten yuan a pot.

It should be an ordinary orchid.

You're an orchid plant, a very common orchid. You are like a spider plant, it's worthless, a pot of about dozens of yuan!

You can't see anything just by looking at the leaves, you have to combine the flowers to know.

You are an orchid grass, a very ordinary orchid, not worth much, we have a lot of it on the mountain. Orchid varieties are expensive, such as tiger head orchid, which is the top grade, and there are thousands of them. You are like a spider plant, it's worthless, about ten yuan a pot!

Isn't this a pot of flowers? But I don't know what flowers are.

This is the legendary daffodil magnolia flower.

A plate of orchids, some orchids are very valuable, a plate can be bought for thousands, a plate costs dozens of yuan, you can buy hundreds like that.

There are many varieties of orchids, and they can't be seen clearly from the **, so they should go to the flower market to see them by themselves, and find a professional to see them, otherwise they will bear the consequences, and orchids are not something that ordinary people can distinguish clearly.

Surprise, is this a close relationship? You have to talk to your mom and don't have a problem.

This is an orchid, there are many varieties, and you only know what kind of variety it is after it blooms.

From the ** point of view, it is difficult to judge what kind of orchid this is called, there are many varieties of orchids, and it is not easy to say how much it is worth! It costs about 50 yuan to buy a pot of ordinary orchids, so you can go to the market to consult before buying.

op r1，r2

In general, when the design of Senfeng is directed, OP has a certain length, and R1 and R2 also have a certain length.

If this fails, the CPU in the first is only 4 registers, so R1 and R2 only need 2 bits to represent; If there are 1024 registers, 10 bits are required to represent; Suppose the OP length is 8; So the instruction lengths are.

Therefore, the more registers, the longer the instruction length, that is, the operand length, that is, the bit length of the operand specifier;

sn=(an)^2+nan

an=0, the symbol and the title.

an≠0 (except A1).

When n=1, a1=s1=(a1) 1+a1a1=0, and when n=2, a1+a2=(a2) +2a2(a2) 2+a2=0

a2=-1s(n+1)=[a(n+1)]^2+(n+1)*a(n+1)a(n+1)=s(n+1)-sn

a(n+1)]^2+(n+1)a(n+1)-(an)^2-nan[a(n+1)+an][a(n+1)-an]+n[a(n+1)-an]=0

a(n+1)-an is not equal to 0, otherwise it would not be very interesting.

The two sides go about a(n+1)-an

a(n+1)+an=-n

a(n+2)+a(n+1)=-n+1)

Subtract: a(n+2)-an=-1

The interval is equal to the difference series with a tolerance of -1

When n=2k-1 (k is a positive integer).

an=a(2k-1)=a1+（k-1)*(1)=1-k=(1-n)/2

When n=2k (k is a positive integer).

an=a2k=a2+(k-1)*(1)=-k=-n 2, i.e. an=0 or.

an={(1-n) 2, n is an odd number.

n 2 , n is an even number.

It's not a matter of asking for one thing, I want to ask for one thing, although this matter is not difficult, but I want your help, my umbrella I am like this, no matter what, right, do it, what to do? As long as it's done, it's okay, please help me take a look, okay? Am I right?

It seems to be a coin of Taiwan. If it's not right, get an expert. went. Let's set it.

Now there are experts in the forensics, and you ask them to show you if it's real or fake.

This is a coin issued in Taiwan.

This doesn't seem to be a commemorative coin, it seems to be a souvenir, and there is no dynasty.

9 years, when there was packaging, the post office sold for 5 yuan,

No, no matter how you add it, it's singular.

15+15=30 didn't say three must be filled, right?
