Betty's best friends likes to do the same thing as she does.改同义句Betty and her best friends have something_____ ______. 三角形ABC的三边分别为a,b,c,边BC上的中线记为m,用于弦定理证明,m=1/2根号2(b^2+c^2)-a^2急、拜托叻、、嘻嘻 she likes fruit and___,oranges.after allabove allin allat all请您分析一下这个句子的意思以及对上述四个进行辨析.翻译:A visit to such schools will leave you in no doubt that the children enjoy themselves. a的平方减5a加6 还有它的提取公英式相应的定理 3q 一a的2次方+5a减6=一(a的2次方减5a减6)对吗?这样添加括号 已知函数f(x+1)=x²-3x+2,则f(x)=? 翻译:He only likes collecting sports things he likes running 和 he likes run那个对?英语考试我写了he likes running.可是上面却打了一个大红x.到底哪个对? He likes to wear a red T-shirt.Ben likes blue best.翻译 lim(x→∞)[(X^2+2x+5)/(3x^2-x+1) = 3a+a=4a 是不是方程?是不是一元一次方程?3(a+1)=3a+3呢 怎么解这个a+2a^2+3a^3+4a^4+.+na^n方程啊 直角三角形射影定理是几年级学的 Jack likes to eat chicken very much改成疑问句 My mum likes swimming very much.改为一般疑问句并做肯定和否定回答. 一道初三的一元二次方程.x^2-4ax+3a^2=1-2a承 求多项式2x的2次幂+3x-2分之1与4x的2次幂-4x+2的差 改为现在进行时She often runs behind her lovely dog对a lovely rabbit提问 现在进行时的关键词有哪些 如often She relaxed her mind by listening to music.这句话可以加上often 如果变成现在进行时该怎么样变? 因式分解a的平方+5a+ba的平方+5a+b2x的平方-x-36x的平方+7x-5 因式分解5a的平方加a加一 已知:f(x)=㏒3 (x^2+ax+b)/x,x属于(0,+∞).是否存在实数a,b,使f(x)同时满足下列两个条件:(1)f(x)在(0,1)上是减函数,[1,+∞)上是增函数;(2)f(x)的最小值是3,若存在求出a b,若不 已知函数f(x)=x^3-ax-1是否存在实数a使f(x)在(-1,1)上单调递减 已知f(x)=log3 x2+ax+b x ,x∈(0,+∞),是否存在实数a、b,使f(x)同时满足下列两个条件:(1)f(x)在(0,1)上是减函数,在[1,+∞)上是增函数;(2)f(x)的最小值是1,若存在,求出a、b,若不 已知f(x)=log3[(x^2+ax+b)/x],x∈(0,+无穷),是否存在实数a,b,使f(x)同时满足下列三个条件.①在(0,1]上是减函数,②在[1,正无穷)上是增函数,③f(x)的最小值是1?若存在,求出a,b的值,若不存在,请说 已知实数x、y满足x^2+4xy+4y^2+x+2y-6=0,求6/(x+2y)的值急 C语言中,平方怎么表示平方怎么表示,是不是还得调用math库中的函数,求解答 无论xy为何实数,x^2-4xy+6y^2-4y+3的值是A 正数,B 负数,C 0,D 非负数 my mother often does housework in the morning (用now把句子改为现在进行时 ) my mother often does homework in the morning.用now把句子改为现在进行时 My mother often does housework否定句和一般疑问句
