What is the equation of a horizontal ellipse with a center at point (-2,4), a major axis that is 8 units long, and a minor axis that is 4 units long? 1.)(x+2)2/8+(y-4)2/4=1..2.)(x+2)2/4 +(y-4)2/16=1..3)..(x+2)2/16+(y-4)2/ 4=1..4)..(x-2)2/16+(y+4)2/4=1

what? that isnt a question

step-by-step explanation:

~dasgupta/mathbook/append17dec2k8.pdf

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
