PEP sixth grade volume II Chinese Lesson 11 "lighting" exercise book answers
It's mainly the second of the four questions,
"It's said that as soon as the button is pressed, the thing lights up. It's very bright." he struck a match again, lit a cigarette, looked at the picture, and said affectionately, "tomorrow's victory, we can also use the electric light, so that the children can learn in such a bright light."


The first time was a night before the Qingming Festival, when "I" was walking in Tiananmen Square. Suddenly, an exclamation came from behind: "how nice!" the person who said this may have come to Beijing for the first time, or a few years later, to see the beauty of Beijing and the happy life of the people. "How nice!" is a praise from the heart
The second time was before the battle, deputy battalion commander Hao was reading a broken book by the light of a match. The illustration in the book showed a child reading under an electric light. "How nice" was the self talk of deputy battalion commander Hao when he read the illustration. At this time, he might think that after victory, the people would live a happy life. Maybe he would touch the scene and make up his mind to win the battle and live a better life for the next generation, Go forward bravely, not afraid of sacrifice
The third time is what deputy battalion commander Hao said when talking with "I." how nice "is his vision for a happy life in the future." if we win tomorrow, we can also use the electric light, so that the children can learn under the bright light. "

It is known that the sum of the two equations (a + C) x2 + 2bx - (C-A) = 0 is - 1, and the difference between the two equations is 1, where a, B and C are the three sides of △ ABC. (1) find the root of the equation; (2) try to judge the shape of △ ABC


(1) Let two of the equations be x1, X2 (x1 > x2), then X1 + x2 = - 1, ①, x1-x2 = 1, ②, ① + ② get 2x1 = 0, X1 = 0, ① - ② get 2x2 = - 2, X2 = - 1; (2) ∵ X1 + x2 = - 1 = - 2BA + C, x1x2 = a − Ca + C = 0, ∵ a-c = 0, 2b = a + C, ∵ a = C, 2b = 2A = 2C



In rectangle ABCD, ab = 3 times root 3, BC = 3, fold triangle BDC along diagonal BD to move C to E
AB = 3 times the root 3, BC = 3 fold the triangle BDC along the diagonal BD, so that C moves to e, and the projection h of point E on the plane abd is exactly on AB, so as to find the distance from a to the plane BDE


The projective h of ∵ point E on the plane abd is exactly on ab ∵ eh ⊥ plane abd ∵ eh ⊥ ad ⊥ ab ⊥ ad ⊥ plane Abe ⊥ ad ⊥ AE ⊥ AE ﹥ AE ﹥ 178; = de ﹥ 178; - ad ﹥ 178; = CD ﹥ 178; - BC ﹥ 178; = ab ﹥ 178; - be ﹥ 178; = 27-9 = 18 ∵ Abe is a right triangle AE = 3 √ 2. Let a be the distance from plane BDE



Factorization of 2x ^ 3-1 / 4

It is proved that nnnnn-5nnn + 4N can be divided by 120 when n is an integer greater than 2


Nnnnn-5nnn + 4N = n (nnnn-5nn + 4) = n (nn-4) (nn-1) = n (n + 2) (n-2) (n + 1) (n-1) is the product of five continuous natural numbers. At least one is a multiple of three, one is a multiple of five, one is a multiple of four, one is a multiple of two, and the other is a multiple of 120. I don't know how to ask. Thank you. Remember to like it



Let p be the point on the ellipse x2 / 25-y2 / 16 = 1, F1 and F2 be the focus. If ∠ f1pf2 = 30 °, then the area of △ f1pf2 is

Two prime numbers
Right?


Impossible, two numbers with sum 97 must be odd and even, and two prime numbers are required. Even number must be 2, and the other one can only be 95 = 5 * 19, so it is impossible



We know the square of the function FX = ex (x + ax-a, where a is a constant) 1. When a = 1, we find the curve y
We know the square of the function FX = ex (x + ax-a, where a is a constant) 1. When a = 1, we find the tangent equation of the curve y = FX at the point (1, F1). 2. If there is a real number k, so that the equation FX = k about X has two unequal real roots on [0, positive infinity), we find the value range of K
