Bài 5:
d: Áp dụng tính chất của dãy tỉ số bằng nhau, ta được:
\(\dfrac{x}{2}=\dfrac{y}{3}=\dfrac{z}{4}=\dfrac{x+y-z}{2+3-4}=\dfrac{-20}{1}=-20\)
Do đó: x=-40; y=-60; z=-80
a: BC=căn 6^2+8^2=10cm
bD là phân giác
=>AD/AB=CD/BC
=>AD/3=CD/5=(AD+CD)/(3+5)=8/8=1
=>AD=3cm; CD=5cm
b: Xét ΔBHA vuông tại H và ΔBAC vuông tại A có
góc B chung
=>ΔBHA đồng dạng với ΔBAC
=>BH/BA=BA/BC
=>BH*BC=BA^2
c: Xét ΔBHA có BI là phân giác
nên IH/IA=BH/BA
=>IH/IA=BA/BC=AD/DC

Em bị deadline dí à :))?? Mấy cái này chỉ cần quy đồng, nhóm hay chuyển vế gì là ra mà, em phải tự làm trước , câu nào không hiểu hay không biết làm thì mới đăng chứ!
A=\(\dfrac{1-\sqrt{x}}{\sqrt{x}\left(\sqrt{x}+2\right)}.\dfrac{\left(\sqrt{x}+2\right)^2}{1-\sqrt{x}}\)=\(\dfrac{\sqrt{x}+2}{\sqrt{x}}\)
