9x-9y=-9
x-y=-9/9
x-y+1=0.......(1)
4x-3y=-8
4x-3y+8=0....(2)
combining equation we get
(x-y+1)(4x-3y+8)=0
x(4x-3y+8)-y(4x-3y+8)+4x-3y+8=0
4x²-3xy+8x-4xy+3y²-8y+4x-3y+8=0
<u>4x²+3y²-7xy+12x-11y+8=0</u><u> </u><u>is</u><u> </u><u>your</u><u> </u><u>equation</u><u>.</u>
Answer:
42
Step-by-step explanation:
The perimiter is 4 times as great as the lenght of any of its sides means that:
4 * a (perimiter) = 4 * a (4 times any of the sides)
It means that one side is 1/4 of the perimeter:
a = 1/4 * 4a
a = a
Answer: Perimeter is proportional to the side length by Perimeter = 4 * Sides or Side = 1/4 Perimeter.
