Can anyone explain it to me?? Can anyone help me explain ...

Li Shangyin's Untitled translation is: Last night the stars were shining, the wind was like water, I wandered to the west of the painting building, and all I thought about was you who lived in the east of Guitang. Although we are close at hand, it is as if we are separated by the end of the world; I hate myself, I don't have wings like a colorful phoenix to fly freely with you, and I can be glad that you and I are heart-to-heart with each other, and we know each other. 」

This is an untitled poem with the author's own direct appearance, which is written about the spring breeze last night; The deep nostalgia of the intended person who rotates into an interval. The first two sentences are reminiscent of last night from tonight's scene. It's a beautiful spring night :

The stars twinkle, the breeze is breezy, the air is filled with an intoxicating warmth, and everything seems to be the same as last night. The third and fourth sentences return to the present by reminiscing about last night, expressing the separation of the present night and the complex and subtle psychology caused by it. The two sentences said that although they did not have the wings of Caifeng on their bodies, they were able to fly over the barrier and meet each other, but each other's hearts were like supernatural rhino horns, and they had a thread of communication.

I think the upstairs ones are okay, so I don't need to be in anything.

True/False? That is to say, the 2 sides of the triangle ab+ac = 2 times the length of the midline 2ad

Patently wrong.

Because :ab=16cm, n is the midpoint of ab, so:an=8cm.

Because ac:cb=3:5, so:ac=3 8ab=6cm.

m is the ac midpoint, so am = 3cm.

mn=an-am=8cm-3cm=5cm

One is multiplied by x 2 equals that answer.

The equivalent of a multiplier multiplied by another multiplier equals the product.

Then one of the multipliers can be calculated by division.

Divide the product by one of the factors to find the other.

The answer and the process of answering it can be found in **.

Earning, networking, and explanation, is to think on the basis of observation, and reasonably explain the reasons for the change of things, the connections between things, or the laws of the development of things.
