Add a number to the molecule of 16 / 9, and subtract the number from the denominator at the same time. The new number is reduced to 3 / 2. What is the number

If you subtract a number from the denominator and divide it into 3, you need to subtract 1, 4, 7, 10 and 13
The denominator is 15,12,9,6,3
And the molecules add the same number,
They are: 10,13,16,19,22
Only 10 / 15 = 2 / 3, so the number is 1

They are not______ the same class,but they are______ the same school.
A.on;in B.in;in C.in;at D.at;in

B

(-4a^6-20a^4b^2-12a^3b+6a^3b^2)/[-(-2a)^3]

(-4a^6-20a^4b^2-12a^3b+6a^3b^2)/[-(-2a)^3]
=(-4a^6-20a^4b^2-12a^3b+6a^3b^2)/（8a^3）
=-1/2a³-5/2ab²-3/2b+3/4b²

G is the center of gravity of triangle ABC, where AG is 3cm, BG is 4cm, CG is 5cm, find the area of triangle ABC,

Because the middle line of a triangle divides the triangle into two parts with equal area, it is easy to prove that AG, BG and CG divide △ ABC into three parts with equal area. Note that the middle point of BC is D, and the two segments of the middle line AD are known as Ag = 2Gd. Extend GD to h, and make DH = Gd, connect Hb, then △ DBH ≌ △ GDC, Hb = CG = 5, and △ GBH and △ GBC have the same area
