Bill Ch'ng is a member of the Science Club and he has to hang a poster on a wall to recruit new members.
The poster is rectangular and its coordinates are at ( 4 , 2 ) , ( 7 , 8 ) , ( 7 , 2 ) , ( x , y )
What is x + y ?

All i did was just pairing the numbers up e.g. there are pairs of 2 and 7 and what's left unpaired are 8 and 4 so therefore the answer is 4+8 = 12
i did graphically too
i realy enjoy
according to coordinate geometry formula of third vertex thevalue of x is 4 and that of y is -4. then ans is 0

But nothing beats graphing it bro :) Try it, it's really clear :D
Yes the answer should be 0. Because x=4 and y= -4.
I' m nt gettng plzz explan mee clearly ths quest.

the poster is square so you can assume that the line of two point (example (7,8) and (7,2) is parallel to (4,2) and (x,y); and (7,2) and (4,2) parallel to (7,8) and (x,y) ; then find the intersection ) then add the value of x and y....
kajal tomar.....ask chris boyd he did graphically too.......
I also do graphically.
i do it graphicaly because its a rectriangular therefore its esay
this might help:
4+2=6 7+2=9 8+7=15
obviously the interval that can equate each coordinates would be 3. and so 9+3 =12 :D
i have solved this problem analytically,this is clear solution,one can get it easily
line intersecting from 4,2 and 7,8 makes the co ordinates 4,8 and it forms a rectangle so 4+8 = 12
(4,2) is the first coordinate,(7,2) & (7,8) are the 2nd & 3rd coordinate respectively,last coordinate must be(4,8) since it is a rectangle.(x,y)=(4,8)=12
just by drawing the graph and you''ll get the coordinates..
Graphically If we do it, we get it X co-ordinate 4 and Y Co-ordinate 8 which will create rectangle precisely. Hence it clearly implies a value of X+Y is equal to 4+8=12.
using graph, we can solve this.. by plotting the given co-ordinates
the all 4 points of rectangular ar at the right positive side ,so the remaning point is complimentry to the other 3 points ,the remaning point is (x,y)=(8+4)=12.
1ST COORDINATE IS (4,2) 2ND IS (7,2) 3RD ONE IS (7,8) THEN 4RT ONE IS (4,8) AND 4+8=12
By logic, if I'm joining the values of (4.2) and (7.8), the progression appears in (7.2) therefore only be wanting (4.8) that when added result 12
the picture is 3 units long and 8 unit high so the other co-ordinate will be (4,8) so x+y=4+8=12.
The answer is a simple pattern. The right digit was 4,8,4, so the next one is 8. The left digit was 4,7,7, so the next was most likely 4. 4+8=12.
one vertex is at (4,2) and near to it is (7,2). above (7,2) is vertex (7,8)..... so above (4,2) will be vertex (4,8) and hence (x,y)=(4,8) and x+y=4+8=12
just draw the rectangle you can find the co-ordinates for the fourth point and then just add those
(7,8) e (7,2) tem mesmo X(a semirreta que as une, portanto é paralela ao eixo Y) e Y que varia de 2 a 8 . Para formar um retângulo o ponto(x,y) deve formar , com o ponto (4,2), uma semirreta paralela ao eixo Y (ou seja, com o mesmo X que esse ponto) , a semirreta também deve ter Y que varia de 2 a 8, portanto o ponto é (4,8)
can you translate it into english

yes i can .bt what
you can use Google converter.

by drawing graph we get (4,8) the 4th coordinate.
