Hi, I think it might be:
A) 10000000+700000+20000+7000+400+90+5
B) ten million, seven hundred and twenty seven thousand, four hundred and ninety five.
The answer is (1) because 7,300,000-3,900,000 is 3,400,000
The greatest common factor would be 8
Step-by-step explanation:
The rule for a 90 degree counterclockwise is
(x,y) -> (-y,x)
so
C(-1,2) -> C'(-2,-1)
D(3,5) -> D'(-5,3)
E(1,2) -> E'(-2,1)
2 3/2 is not equal to any of these
