Punctul 1 y. Rezolvare completa. Va rogggggggggg va implor e urgent

Answer 1

$x = ( \frac{15}{5 \sqrt{3} } + \frac{18}{6 \sqrt{3} } + \frac{33}{11 \sqrt{3} } ) \times 5 \sqrt{3} = \frac{9}{ \sqrt{3} } \times 5 \sqrt{3} = 9 \times 5 = 45$

$y = 2(11 - 9)(3 \sqrt{2} - 3)(3 \sqrt{2} + 3) = 2 \times 2(9 \times 2 - 3) = 2 \times 2(18 - 3) = 2 \times 2 \times 15 = 60$

La punctul a am aratat mai sus

acum fac punctul b)

$b)45 = \frac{p}{100} \times 60 \\ 45 = \frac{3p}{5} \\ p = 75$
