Mọi người ơi giúp mik với ai làm đc mik tick , làm đc câu nào mik tick cho
a, Áp dụng t/c dtsbn:
\(\dfrac{a}{b}=\dfrac{c}{d}=\dfrac{a+c}{b+d}\)
b, Áp dụng t/c dtsbn:
\(\dfrac{a}{b}=\dfrac{c}{d}=\dfrac{2021a}{2021b}=\dfrac{2021a-c}{2021b-d}\)
c, Ta có \(\dfrac{a}{b}=\dfrac{c}{d}\Rightarrow\left(\dfrac{a}{b}\right)^2=\left(\dfrac{c}{d}\right)^2\)
Áp dụng t/c dtsbn:
\(\left(\dfrac{a}{b}\right)^2=\left(\dfrac{c}{d}\right)^2=\dfrac{a^2}{b^2}=\dfrac{c^2}{d^2}=\dfrac{a^2+c^2}{b^2+d^2}\)

Giúp mik làm câu c với ạ. Mik cảm ơn
72-3.|x|=9 -12(x-5)+7(3-x)=9 (Mik thi nên làm ơn giúp mik mỗi người làm câu hỏi sai hay đúng mik cũng rất cảm ơn)
\(72-3\left|x\right|=9\)
\(3\left|x\right|=72-9=63\)
\(\left|x\right|=63:3=21\)
\(\Rightarrow x=\pm21\)
\(72-3\left|x\right|=9\)
\(3\left|x\right|=63\)
\(\left|x\right|=21\)
x= 21 hoặc x= -21
\(-12\left(x-5\right)+7\left(3-x\right)=9\)
\(-12x+60+21-7x=9\)
\(-19x=-72\)
\(x=\dfrac{72}{19}\)
