I have a question, please ask everyone, thank you for your help in advance, hehe

It is not enough to have resourcefulness, but also to understand the art of power, etc., they understand their own shortcomings and position themselves.

This brings us to organizational skills. And at that time, I also talked about my origin.

In addition, most of the people at that time were loyal people, unlike today's society. At that time, people would have wondered why that person would have rebelled, but now people are wondering why that person would not rebel.

Solution: Pythagorean number 3, 4, 5, group 6, 8, 10, 5, 12, 13, group, 7, 24, 25 group, 8, 15, 17, group, 9, 40, 41, group.

What's the problem? I didn't get it.

The solution of this indefinite equation seems to have a formula:

x＝m² -n²，y＝2mn，z＝m²＋n²。

We can understand it this way, AB is a horizontal line, through the point C to make an auxiliary surface PH perpendicular AB, and PH is a plumb plane, AB is perpendicular to all straight lines in pH, then the intersection point D of AB and PH plane, connecting CD, that is, CD intersects vertically at AB. Obviously, ph is projected as a clustered straight line on the h-plane, and the h-plane is also perpendicular to ab.

Synonym. Origin emphasizes the starting point, and ** emphasizes the process.

Addendum: In addition to the fact that the two words describe the process of development of things at different stages, there are two other differences:

1. The origin is unique, and the first is diverse. If you can say that it is important, main, one of them, etc., the origin cannot.

2. There is a difference in the part of speech. In addition to being used as a verb, ** can also be used as a noun.

nt is the English abbreviation, Chinese is the thickness of the transparent membrane of the neck, under normal circumstances, the thickness of this membrane in the first trimester is below, and will disappear in the second trimester, and the Down's baby will be abnormally thickened, so B ultrasound measurement of the membrane thickness can screen for Down's child.

1. Missing a key description [Blocks submerged in water]!!

2. The answer to the question after it has been completed:

Solution: v=m to v=m to find the volume of water:

v'=m'/ρ'= 1000g (, by v=vo-v.)'Find the volume of the block:

v=vo-v'=1500cm -1000cm =500cm, find the density of the block by =m v:

m/v=1300g/500cm³=。

A: --

6 5 2 = 60 cubic decimeters.

Because 1 cubic decimeter is equal to one liter.

All equal to 60 liters.

60 RMB.

Take advantage of the condition of the triangle inner angle and 180 degrees.

Sensory deficiency, about 30 degrees.
