Question

Finds the value(s) of c if...

Answer 1

\[\frac{a+b}{b+c}=\frac{c+d}{d+a}\]

Answer 2

\[\frac{-b-d \pm \sqrt{b^2+2bd+d^2+4a^2+4ad+4ab}}{2}\]

Answer 3

tricky c = a

cross multiply
a + b = b + c
a = c

Answer 4

the answer is 5, or -5-b-d, but i have no idea how to get there

Answer 5

weird they they could come up wth a value like 5 if no numercal values provided by others?

Answer 6

i have no idea either, i'm guessing it's a mistake because c could equal any number

Answer 7

How does c = a?

Answer 8

cross multiplied and assume that one side equal other side

Answer 9

I put it in Wolfram and they solved it by completing the square and got the same thing I got by using the quadratic formula.
