As shown in the figure, there are four rectangular and square cards. Please use these four cards to make a square
As shown in the figure, four cards are rectangular and square. Please use these four cards to make a square. Requirements: there should be cards of each type in the puzzle, and there should be no overlap between the cards. Draw a diagram of your composition, and calculate its area (expressed by an algebraic formula containing a and b)
A large square with side length a
Two rectangles, both a in length and B in width
There is also a small square with a side length of B

How many can you spell a rectangle with 24 identical squares

4. 1 * 24 2 * 12 3 * 8 4 * 6

How many earth sizes does a Jupiter have?

There are 1316 earth sizes

How big is Jupiter on earth?
Is it as big as the moon

The apparent diameter of the moon is about + 2 ° 8'16.9 ", which can be seen clearly with the naked eye
Jupiter's apparent diameter is about + 0 ° 0'39.0 ", which you can barely distinguish if you have excellent eyesight

It is known that a circle passes through points a (3,0), B (- 1 / 5,8 / 5), and the chord length obtained by cutting x-axis is 2. The equation of this circle is obtained

Center (a, b), radius r, distance from center to chord y = 0, d = | B|
(a-3)^2+b^2=r^2...1)
(a+1/5)^2+(b-8/5)=r^2...2)
D^2+(2/2)^2=r^2=1+b^2...3)
1)-2):2a-b-2=0...4)
1)-3):a^2-6a+8=0
A = 2, B = 2, R ^ 2 = 5 or a = 4, B = 6, R ^ 2 = 37
The equation of circle
(x-2)^2+(y-2)^2=5
Or (x-4) ^ 2 + (y-6) ^ 2 = 37

Given that the radius of the center of the circle on the x-axis is 5 and the chord with a (5,4) as the midpoint is 2 and the root sign is 5, the equation for finding the circle?
It seems that I have two solutions, C (3,0). C (7,0). But in other people's questions, there is only one answer. Is it me or they who are wrong,

I calculated. Both. Is there any special requirement in the question? No, just both

Quadratic function problem: in triangle ABC, angle B = 90 °, ab = 6cm, BC = 12cm
The moving point P starts from point a and moves at 1 cm / s along the edge AB to B, and the moving point Q starts from point B and moves at 3 cm / s along the edge BC to C. It is known that P and Q start from a and B respectively. When p goes to B or Q goes to C, P and Q stop moving at the same time
The results are as follows: 1. The analytic expression of the function between the area s of triangle pqb and the moving time t and the value range of T;

The analytical formula is: S = 0.5 * (6-T) * 3T
The value range of T is: 0 〈 t

The area of diamond is 83cm, the ratio of two diagonal lines is 1:3, then the side length of diamond is______ cm．

Let the lengths of the two diagonals be x, 3x, 3x2 = 163, and the solution is x = 4. The lengths of the two diagonals are 4 and 43 respectively. According to the Pythagorean theorem, the side length of the diamond is 4 + 12 = 4cm, so the answer is 4

It is known that the rhombus has an acute angle of 60 ° and the length of the diagonal opposite the angle is 2cm, then the area of the rhombus is CM & # 178;
