Hello, please consider the following.

$\displaystyle \lim_{x\rightarrow3}~\dfrac{2x^2-18}{x^2-3x} \\ \\ \\ =\lim_{x\rightarrow3}~\dfrac{2(x^2-3^2)}{x(x-3)} \\ \\ \\ =\lim_{x\rightarrow3}~\dfrac{2(x-3)(x+3)}{x(x-3)} \\ \\ \\ =\lim_{x\rightarrow3}~\dfrac{2(x+3)}{x} \\ \\ \\=\dfrac{2(3+3)}{3}\\ \\ \\=\dfrac{2*3*2}{3} =\Large \boxed{\sf \bf \ 4 \ }$

Thank you

choose all answer that's are correctall trapezoids are quadrilateralsall rhombuses are parallelogramall rectangles are squaresal

Alexxandr [17]

EXPLANATION

The right options are:

(1) All trapezoids are quadrilaterals because trapezoids are four-sided polygons, so they are all quadrilaterals.

(2) All rhombuses are parallelogram because they are quadrilaterals (plane figure, closed shape, four sides) with four equal-length sides and opposite sides parallel to each other.

(4) All squares are parallelogram because they fulfill criteria of being a rectangle because all angles are right angle and opposite sides are equal.
