First you would ✖️5 twice which is 25 and then you ✖️2 twice which is 4 so 25 - 4= 21 then divide by 3 and it'll = 21

The equivalent expression is ~

${x}^{2} - 7x + 10$

$\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}$

$(x - 2)(x - 5)$

$\small(x \times x) + (x \times - 5) + ( - 2 \times x) + ( - 2 \times - 5)$

${x}^{2} - 5x - 2x + 10$

${x}^{2} - 7x + 10$

Answer:

$x = 3\sqrt{2}$

$y = 6\sqrt{2}$

Step-by-step explanation:

The triangle is a 30-60-90 right triangle.

The ratio of the lengths of the sides is:

$1 : \sqrt{3} : 2$

The order of the sides in the ratio above is

short leg : long leg : hypotenuse

The long leg is sqrt(3) times the length of the short leg.

$x \times \sqrt{3} = 3\sqrt{6}$

$x = \dfrac{3\sqrt{6}}{\sqrt{3}}$

$x = 3 \times \sqrt{\dfrac{6}{3}}$

$x = 3\sqrt{2}$

The hypotenuse is twice the length of the short leg.

$y = 2 \times 3\sqrt{2}$

$y = 6\sqrt{2}$
