In a parallelogram ABCD, if the lengths of the three consecutive sides are x + 2,3x-1,6-x respectively, what is the circumference of the parallelogram ABCD?
Hurry up

X + 2 = 6-x, the solution is x = 2, then the side length is 4,5,4,5 respectively, and the perimeter is 18

A simple algorithm for 1999 × 1999-1998 × 1998

1999×1999－1998×1998
=(1999-1998)(1999+1998)
=2000-1+2000-2
=4000-3
=3997

An investor buys 1000 shares of a stock in Shanghai at the price of 10 yuan per share. When the stock rises to 12 yuan, all the shares are sold. What is the actual profit of the investor?
How do I figure it out

According to the topic, every time you buy and sell in the transaction, you need to pay 7.5% of the intermediate cost, so you need to subtract the profit from the intermediate cost of every time you buy and sell
(12-10)*1000 - 10*1000*0.75%- 12*1000*0.75%
=2000-75-90
=1835 yuan

Quadrilateral ABCD is a parallelogram, AC and BD intersect at O, DB, vertical ad, BF, vertical CD, OB = 1.5, ad = 4, find the length of DC and BF

In the parallelogram ABCD, ad is parallel and equal to BC equals 4, BD equals 2BO = 3, angle ADB = angle CBD = 90 °. In the right triangle BCD, BC = 4, BC = 3, according to the Pythagorean theorem, CD square = BC square + BD square, namely CD = 5

The order of magnitude of a number is the power of 10 it contains. The mass of Saturn is 5.69 * 10 ^ 29kg, and the mass of earth is 5.9742 * 10 ^ 21kg
How many times the mass of Saturn is that of earth

The order of magnitude is 10. Saturn has 29 10, earth has 21 10,
The magnitude of Saturn's mass is 29 △ 10 = 2.9 times that of the earth
