x(x2+3x+9)-3(x2+3x+9)+5x-x3=6x
x3+3x2+9x-3x2-9x-27+5x-x3=6x
5x-27=6x
5x-6x=27
-x=27
=>x=-27
Câu 1 : Bạn A làm như thế là sai , cô giáo nhắc nhở học sinh là rất quan tâm để ý đến bạn A nhưng A ko nghe và sửa đổi = nghĩa với việc A ko coi trọng cô giáo
-Nếu em là A em sẽ đứng lên xin looix cô và từ sau sẽ ko nói chuyện riêng ảnh hưởng đến h học nữa
Câu 2 :
- Em ko đồng tình vì bà T là nổi tiếng bán bánh ngon mọi người rất tin tưởng bà sẽ làm ra những chiếc bánh ngon , nếu bà ra chợ mua bánh đấy nhỡ ko giống khẩu vị hay tính đặc trưng của quán khách ăn sẽ ko vừa ý nên làm như thé ko đc

\(n_{Al}=\dfrac{10,8}{27}=0,4\left(mol\right)\)
a.
\(2Al+6HCl\rightarrow2AlCl_3+3H_2\)
0,4->1,2----->0,4-------->0,6
\(V_{H_2}=0,6.22,4=13,44\left(l\right)\)
b. \(C\%_{HCl}=\dfrac{1,2.36,5.\left(100+20\right)\%}{200}=26,28\%\)
c. \(n_{HCl.dư}=(\dfrac{200.26,28\%}{100\%}:36,5)-1,2=0,24\left(mol\right)\)
\(C\%_{HCl.dư}=\dfrac{0,24.36,5.100\%}{10,8+200-0,6.2}=4,18\%\)
\(C\%_{AlCl_3}=\dfrac{0,4.133,5.100\%}{10,8+200-0,6.2}=25,48\%\)
a) 18/24+35/-10
=3/4+(-7/2)
=6/8+(-28/8)
=6+(-28)/8
=-(28-6)/8
=-22/8
=-11/4
b: \(=\dfrac{-1}{9}+2=\dfrac{18}{9}-\dfrac{1}{9}=\dfrac{17}{9}\)
c: \(=\dfrac{-4}{7}+\dfrac{-5}{6}=\dfrac{-24-35}{42}=-\dfrac{59}{42}\)
