I really want to be a six-year-old;
That time, I hated;
I don't want to grow up;
That time, I shed tears;
Summer night · missing
You can also write about what you saw and heard during the journey, unforgettable and happy things, and feelings of reading
Note: the above topics are the ones that I have won awards for. It's hard for me to type so many words. Please give them to me!

Composition: I no longer - this is a semi topic composition, just need you to tell me the title of the composition on the line
Does this composition focus on the past or the present?

I am no longer sinking, I am no longer happy, I am no longer helpless, I am no longer naive
There are two ways to write it: 1. Past and present (the sense of progress of the times) 2. Present and past (full of memories)

It is known that the lengths of three sides of triangle ABC are 3 / 2,2,5 / 2, and the maximum length of similar triangle DEF is 25. The area s of triangle DEF is calculated

According to the known triangle ABC three side length is 3 / 2,2,5 / 2, we can know that 1.5 square + 2 square = 2.5 square
Triangle ABC is a right triangle, then the three sides of triangle def are 15, 20 and 25 respectively, area = 15 × 20 △ 2 = 150

Solution equation: X - [6 / 6 x + (6 / 6 x - 50)] = 450

Next time I have to do it by myself. This problem is very simple. How about solving the equation of first degree with one variable
X-1 / 3 x + 50 = 450
2X / 3 = 400
X= 600

A triangle glass, the bottom is 12.5dm, the height is 7.8dm, the price per square meter is 68 yuan, buy this glass to use how many yuan?

12.5 × 7.8 △ 2 △ 100 × 68, = 97.5 △ 2 △ 100 × 68, = 48.75 △ 100 × 68, = 33.15 yuan; answer: it costs 33.15 yuan to buy this glass

1, 2, 4, 8, 16. What's the number in 2013?

If point m is a point in the plane of Δ ABC and satisfies vector AC + 3 * vector AB + 4 and vector Ma = 0, then s Δ ABM:S ΔABC=?
Hope to write out the process```

Vector:
MA+AC=MC,3MA+3AB=3MB
AC+3AB+4MA=MC+3MB=0
So m is on BC
Length:
3BM=MC
BM:BC=1:4
SΔ ABM:S ΔABC=1:4

It is proved that a Λ 2 + B Λ 2 + C Λ 2 + 3ABC / 2 ≥ 9 / 2
Where a, B and C are all positive numbers, and a + B + C = 3

As shown in the figure, in the trapezoidal ABCD, the diagonal lines AC and BD intersect at the point O. if the area of △ cod is A2 and the area of △ AOB is B2, where a > 0 and b > 0, try to find the area s of the trapezoidal ABCD (expressed by the algebraic formula containing a and b)
