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:
°
Step-by-step explanation:
The given figure is a quadrilateral or a figure with (4) sides. The sum of angles in a quadrilateral is (360) degrees. One can apply this here by stating the following:
Simplify,
Inverse operations,
The volume of the original cube = 18^3 = 5,832 cubic cm
5,832 / 8 cubes = 729 cubic cm.
Side length = Cubicroot729 = 9
The side length is 9 cm
Answer:
7/4 yard
Step-by-step explanation:
36 is a suitable common denominator for expressing these fractions. All measures are in yards.
2/3 + 4/9 + 23/36 = (12·2)/(12·3) + (4·4)/(4·9) + 23/36
= 24/36 + 16/36 + 23/36
= 63/36 = (9·7)/(9·4)
= 7/4 = 1 3/4 . . . . . yards
