注:1,3题要详细解答过程。

1.一旅游团队来到某宾馆住宿,该宾馆的房价如下:
双人间 三人间
房价 120元/间 150元/间
导游计算:如果该团体全住双人间,则每间正好5人,如果全住三人间,则最后一间只有1人。
(1)请你帮导游设计一个方案,使他们的住宿费最省。
(2)经导游计算,他们如果全住双人间要比最省的住宿方案多花120元住宿费,问这个团队有多少人?

2.在实数范围内分解因式:
2x^2-6=
x^2-2倍根号2再乘以x+2=
16y^4-24y^2+9=
a^2+(1+根号2)a+根号2=

3.将若干只鸡放入若干个笼,若每个笼放4只,则有一只鸡无笼可放,若每个笼放5只,则有一笼无鸡可放,那么至少有多少只鸡,多少个笼?

4.按要求写出下列各词
dorm(全写形式)——
help(名词)——
terrible(副词)——

5.翻译
丽丽的愿望将会实现。(汉译英)

注:1,3题要详细解答过程。

这是数学:
1、如果该团体全住双人间,则每间正好5人,(这句矛盾)
2、2x^2-6=2(x+根号3)(x-根号3)
16y^4-24y^2+9=(4y^2-3)^2=(2y+根号3)的平方(2y-根号3)的平方
a^2+(1+根号2)a+根号2= (a+1)(a+根号2)
a^2+(1+根号2)a+根号2= (a+1)(a+根号2)
3、解:设有x个笼子。
4x+1=5x-5
-x=-6
x=6
6*4+1=5*6-5=25(只)
答:有25只鸡,6个笼子。

这是英语:
4.dorm(全写形式)—— dormitory
help(名词)—— help
terrible(副词)—— terribly
5.翻译
丽丽的愿望将会实现。(汉译英) Lily's wish will come true.
6.汉译英
1.kill two birds with one stone
2.live like fighing pig
3.be raining dogs and cats
4.Don't count the chickens before they are hatched.
