Yeah I need help. I suck at math.... I'm sure it's easy though

x2 = -64

Step-by-step explanation:

if x2= -64,

then x= 8 because -8 x -8 = +64

please rate it if you got it.!

Khalid and Sue's Height together is 126 Inches. The difference is 6 inches, so therefore you subtract 6 from the total getting you 120 Inches. You do this with all of the problems for example: The first one. Sue is 72 inches and Khalid is 54. Add them together and subtract them by 6 to get your final answer. Please DO NOT quote me on this lol. This is how I read the question. I think this is right but I am not absolutely 100% sure. Hope this helps.
