下列语句中正确的是()表score(sti_id,names,math,English,VB)
已知Eng(1)=90,Math(1)=80,T(1)=2,Total(1)=(Eng(1)+Math(1))/T(1),则Total(1)=()。

编一个程序,输入a,b,c的值,求出一元二次方程a*x*x+b*x+c=0的二个实数根。计算二个实数根必须使用Math类中的Sqrt()方法,计算指定数的开方。计算二个实数根,可以用公式(-b+Math.Sqrt(b*b-4*a*c))/(2*a)和(-b-Math.Sqrt(b*b-4*a*c))/(2*a)
假设math标准库已导入,那么表达式eval(’math.sqrt(4)’)的值为()。
