Số lít dầu nếu chúng cân nặng 5,32 kg:

\(\dfrac{5,32x5,2}{3,952}=7\left(kg\right)\)

Uii, hom có gìii ^^

Hom có gì:>>>>

f(2) = \(2^2+5=4+5=9\)

f\(\left(\dfrac{-1}{3}\right)=\left(\dfrac{-1}{3}\right)^2+5=\dfrac{1}{9}+5=\dfrac{46}{9}\)

Chọn C

= \(\dfrac{\sqrt{3}\left(\sqrt{3}+2\right)}{\sqrt{3}}-\dfrac{2\left(\sqrt{3}+1\right)}{3-1}\)

= \(\sqrt{3}+2-\sqrt{3}-1\)

= 1

-29 - 23 = -52
