9x^2+4y^2+54x+8y-59=0 an ellipse in that needs to be in standard form explain how to do

D

edge

Step-by-step explanation:

The standard form of an ellipse is

Let's try to complete some squares: if we focus on the part involing x, we have

Similarly, for the part involving y, we have

So, the equation becomes

Divide both sides by 144 to get

which is the standard form

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
