A=k/b, where k is a non zero constant.
When a=0.5, b=3.25, is
0.5=k/3.25
k=3.25×0.5=1.625
meaning that when there is a value for b, dividing 1.625 by it will form the value of a.
therefore, when b=2, 1.625/2=0.8125, which is 13/16.
answer is 13/16

Buddy we can't see the line
Hello,
ANSWER B (x^4-3x²-4) [roots are i,-i,2,-2]
3(2+n)-2(5-2n)
Mutiply the first bracket by 3
(3)(2)= 6
(3)(n)= 3n
Mutiply the second bracket by -2
(-2)(5)= -10
(-2)(-2n)= 4n
6+3n-10+4n
6-10+3n+4n ( combine like terms )
-4+7n or 7n-4
Answers: -4+7n or 7n-4
