wel

Answer:

Ellipse

Step-by-step explanation:

Given the equation

$4x^2 +9y^2 =36$

Divide this equation by 36:

$\dfrac{4x^2}{36}+\dfrac{9y^2}{36}=\dfrac{36}{36}\\ \\ \\\dfrac{x^2}{9}+\dfrac{y^2}{4}=1$

The equation of the form

$\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1$

represents an ellipse, so given equation is the equation of the ellipse.

Answer:

$\frac{12a-14b}{21}$

Step-by-step explanation:

Express the 2 fractions with a common denominator of 21

multiply numerator/denominator of first fraction by 3

multiply numerator/denominator of second fraction by 7

$\frac{4a(3)}{7(3)}$ - $\frac{2b(7)}{3(7)}$

= $\frac{12a}{21}$ - $\frac{14b}{21}$

= $\frac{12a-14b}{21}$
