There is a kind of growth called temper, life is like a soul stirring, ups and downs of symphony, the top of the storm, between rumors, is a challenge to self struggle, only in this way, can fade wings, spread wings. In order to complete the practical activities of the newspaper selling experience, I held in my arms

10.24.52.78. (). 164 what are the rules of the numbers in brackets

126
10=3*3+1
24=5*5-1
52=7*7+3
78=9*9-3
164=13*13-5
So () = 11 * 11 + 5 = 126

It is known that △ ABC is similar to triangle def, and ab: de = 1:2. What is the area ratio of triangle ABC to triangle def?

It is known that △ ABC is similar to △ def, and ab: de = 1:2
So the similarity ratio is 1:2, the ratio of high is 1:2, and the area ratio is the square of the similarity ratio (because the area = 1 / 2 bottom * high)
So the area ratio is 1:4

Solving equation 21.3 = 35.1 x-x
The original question is,
（21.3-X）*X＝35.1

21.3 = 35.1x-x21.3 = 34.1xx = 21.3 △ 34.1x = 213 / 341 (213 of 341) (21.3-x) * x = 35.121.3x-x & # 178; = 35.1x & # 178; - 21.3x + 35.1 = 0 (x-19.5) (x-1.8) = 0x-19.5 = 0 or x-1.8 = 0x = 19.5 or x = 1.8

The bottom of a triangle glass is 12. The height is 7.6 decimeters. The price of glass without square meter is 68 yuan. How much does it cost to buy this glass?

What is the area of the glass
12.5 × 7.6 △ 2 = 47.5 (square decimeter) = 0.475 (square meter)
need
68 × 0.475 = 32.3 yuan

Find 1-2 + 3-4 + 5-6 + 7-8 + 9-10 + +2011-2012+2013

The original formula = - 1 + (- 1) + (- 1) + +(- 1) (1006 - 1) + 2013 = 1007

As shown in the figure, the triangle ABC and triangle ade are equilateral triangles. BD and CE intersect at point F.1. Prove: BD = CE; 2. Calculate the degree of acute angle BFC

Because △ ABC and △ ade are equilateral triangles
So AB = AC, AE = ad, ∠ BAC = ∠ ACB = 60 °, ∠ ead = 60 °
Because ∠ ead = ∠ BAC = 60 °
Therefore, bad = EAC
Because AE = ad, ∠ bad = EAC, ab = AC
So △ abd ≌ ace
Therefore, DBA = FCG
Because ∠ DGA is the outer angle of △ ABG and △ FCG
So ∠ bag + ∠ GBA = ∠ DGA, ∠ GFC + ∠ FCG = ∠ DGA
Because ∠ bag + ∠ GBA = ∠ DGA, ∠ GFC + ∠ FCG = ∠ DGA, ∠ ACB = ∠ bag, ∠ GBA = ∠ FCG
Therefore, ACB = GFC
Therefore, GFC = 60 degree
That is, BFC = 60 degree
Because AE = ad, ab = AC ∠ bad = ∠ BAC + ∠ DAC ∠ EAC = ∠ ead + ∠ DAC
Therefore, EAC = DAB
So the triangle EAC is equal to the triangle DAB
So BD = CE, ∠ abd = ace

Known: 3 (a + B + C) = (a + B + C), proved: a = b = C

3 (a + B + C) = (a + B + C) 3A + 3B + 3C = a + B + C + 2Ab + 2BC + 2ca2a + 2B + 2C - 2ab-2bc-2ca = 0 (a-b) + (B-C) + (C-A) = 0 and (a-b) ≥ 0, (B-C) ≥ 0, (C-A) ≥ 0 (a-b) = (B-C) = (C-A) = (C-A) = (C-A) = (C-A) = 0 (a-b = B-C = C-A = 0)
