Write one digit on each side of 36 to make a four digit multiple of 36. how many different solutions does this problem have?

Ineed someone to me answer my question i have to have this done and knocked out

Which function in vertex form is equivalent to f(x) = x2 + 6x + 3? f(x) = (x + 3)2 + 3 f(x) = (x + 3)2 − 6 f(x) = (x + 6)2 + 3 f(x) = (x + 6)2 − 6

Solve 4 ln x=2ln25 a) x=5 b) x=25 c) x=625
