I am a graduate student in the Department of Mathematics.

Here's what the translation looks like.

1. And simplification.

An expression of a quadratic polynomial.

2. Factorization involves common factors, cubic polynomials, polynomial expressions of different square terms3, and solving quadratic equations with real roots.

4. Solve the system of linear equations involving two variables given by the image, and solve the system of linear equations involving two variables given by the algebraic method of substitution and elimination5. Solve the problem involving the length of the inclined plane and the midpoint of the line segment.

6. Determine the radius of the circle equation given the center of the circle

The last two are uncertain and should have context.

You have the right understanding of linear relations and linear equation.

Linear relations are linear relations.

Linear equation is a linear equation.

I don't know anything else, but I'm from a liberal arts background.

Is this an assignment for international students?

This is to say that a curtain rod was erected diagonally in one corner of a room.

a.Add a line and an angle symbol to show the angle at which the curtain rod is formed by the ground.

It is for you to draw a line that can represent the angle between the curtain rod and the ground.

If the dot above 155 is a, the dot below is b, and the dot to the right of 42 is c. The line you need to connect is BC, and he wants you to represent the angle ACB

b.Find the degree of the angle ACB.

c.Find the length of ac.

1. Indicate the angle between the floor and the rod.

2. Calculate the angles in the above question.

3. Calculate the length of the rod.

1.The corner of the wall is connected to the bottom of the rod, and the angle between the rod is the angle you seek.

2.The distance from the bottom end of the rod to the corner of the wall is approximately equal to the angle = arctan (155 3The square and root of length = 155, 42, 27 are approximately equal to.

A construction worker erected a curtain pole in the corner of the room, all in centimeters a Add a linear angular symbol to mark the angle of the curtain rod to the ground (I think it's the line between the pole and the corner of the wall).

b Calculate the approximation of the size of the angle in a (calculating the angle is the angle between the pole and the ground, which is not a problem).

c Calculate the length of the curtain rod and give a reasonable explanation (the problem of finding the side length in a right-angled triangle).

There is a curtain rod in the corner of the room, the dimensions are measured in centimeters, here are the questions.

aAdd line type and corner mark to calculate the angle formed by the curtain rod and the ground.

b calculates the closest value of the parta angle.

cCalculate the length of the curtain rod.

curtain rod. A construction worker placed a curtain rod in the corner. The measured data in the figure are measured by one centimeter.

a A horizontal line and a corner mark are added to the diagram to indicate the angle between the pole and the ground.

b calculates the angle in the previous question to the nearest value.

c calculates the rod length and represents it in the most appropriate whole book.

Hope it helps.

A construction worker has put a curtain pipe in the corner of a room. The size of this figure is in centimeters. One.

Add a line to the symbol to show an angle of the angle with the rod so that the floor B. Partly to calculate the angle (most recent degree. c。

Calculate the length of the rod. round your right.
