Examples of line segments include the sides of a triangle or SQUARE. More generally, when both of the segment's end points are vertices of a POLYGON or polyhedron, the line segment is either an EDGE (of that polygon or polyhedron) if they are adjacent vertices, or a diagonal.

Answer:

323

Step-by-step EXPLANATION:

Given, x = ( √5 – 2 ) / ( √5 + 2 ) and y = ( √5 + 2 ) / ( √5 – 2 )

x = ( √5 – 2 ) / ( √5 + 2 )

= ( √5 – 2 ) / ( √5 + 2 ) × ( √5 – 2 ) / ( √5 – 2 )

= ( √5 – 2 )² / [ (√5)² – (2)² ]

= ( 9– 4√5 ) / ( 5 – 4 )

= 9 – 4 √5

y = ( √5 + 2 ) / ( √5 – 2 )

= ( √5 + 2 ) / ( √5 – 2 ) × ( √5 + 2 ) / ( √5 + 2 )

= ( √5 + 2 )² / [ (√5)² – (2)² ]

= ( 9 + 4√5 ) / ( 5 – 4 )

= 9 + 4√5

Now, x² + xy + y²

= ( 9 – 4√5 )² + ( 9 – 4√5)( 9 + 4√5 ) + ( 9 + 4√5 )²

= ( 81 – 72√5 + 80 ) + [ 9( 9 + 4√5 ) –4√5( 9 + 4√5 ) ] + ( 81 + 72√5 + 80 )

= ( 161 – 72√5 ) + ( 81 + 13√5 – 13√5 – 80 ) + ( 161 + 72√5 )

= 161 – 72√5 + 1 + 161 + 72√5

= 161 + 1 + 161

= 323

Substituting

x=3 and y=2

in the GIVEN equation, we GET LHS =

5×3-3×2=(15-6)=9

RHS

THEREFORE, x=3 and y=2

is a SOLUTION of

5x-3y=9

Answer:70°/°

Step-by-step EXPLANATION:

Answer:

Answer:Mature MAMMALIAN RBC does not contain membrane-bounded CELL ORGANELLES. Mammalian RBC is biconcave, circular, nonnucleated cell. Their cytoplasm is rich in hemoglobin, an iron-containing biomolecule, that can bind oxygen and is responsible for the RED color of the cells. The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiological cell function, such as deformability and stability, while traversing the circulatory system and specifically the capillary network. In humans, mature red blood cells are flexible and oval, biconcave disks. They lack a cell nucleus and most organelles in order to accommodate maximum space for hemoglobin.

ANSWER Of This QUESTION Is 13

Answer:

POINTS B, E, C and F do not LIE on that line. Hence, these points A, B, C, D, E, F are called non - collinear points. If we join three non - collinear points L, M and N lie on the plane of paper, then we will get a closed figure bounded by three line segments LM, MN and NL.

ANSWER:

Step-by-step explanation:

12 m 3 MM

1 m = 1000 mm

1 mm = 1/1000 m

Then 3mm = 3/1000 = 0.003 m

Then 12 m 3 mm = 12 + 0.003 = 12.003 m

ANSWER:

Step-by-step EXPLANATION:

a+b=7

by USING IDENTITY, (a+b)^2=7^2

a^2 +2ab+b^2=49

since ab=17, a^2+2*17+b^2=49

a^2+b^2=49-34

a^2+b^2=15

therefore, a^2-ab+b^2=15-17

= -2

Answer:

Step-by-step EXPLANATION:

let the SUM be P

SI = PTR/100=P*3*15/100=45P/100=9P/20

CI = A-P=P (1+R/100)^n-P=P (1+15/100)^3-P

=P (115/100)^3-P

=P (23/20)^3-P

So by question CI-SI = 283.50

or P ((23/20)^3-1)-9P/20=P ((23/20)^3-1-9/20)=283.50

or P= 283.50/((23/20)^3-29/20)

or P = 4000 (ans)

2/3 + (1/5 + 1/2)

= 2/3 + [(2 + 5)/10]

= 2/3 + 7/10

= (20 + 21)/30

= 41/30 --------(1)

R.H.S.

(2/3 + 1/5) + 1/2

= [(10 + 3)/15] + 1/2

= 13/15 + 1/2

= (26 + 15)/30

= 41/30.
