Hi121529

22 all the coffins open in the end are perfect squares. 

Well it's whatever age the person reading it is . . . so in this case how old I am. 

An echo 

Okay so expanding (1+i)(2+i) we get

2+i+2i+i^2 = 

2+3i-1 = 

1+3i

Multiplying (1+3i)(3+i) we get

3+i+9i+3i^2 = 

3+10i+3(-1) =

10i

Hope that helps!

Did you mean for it to be (2+1) or did you mean (2+i)? Clarify that please and then I'd be happy to help! 

Could you make the question clearer? Are we supposed to be finding when the options are equal to each other? Then I would be happy to help! :)

Thank you so much!!!

Since 67 is a prime number, there are only 2 integer results we can have: 1 and 67.

To get 67, the denominator should be 1.

2x - 23 = 1 

2x = 24

x=12

To get 1 as the integer result, the denominator should be 67.

2x - 23 = 67

2x = 90

x = 45

12 + 45 = 57
