Rectangle ABCD is similar to rectangle EFGH. The rectangles and some of their dimensions are shown in the diagram below.
Based on the dimensions in the diagram , which is the value of x?
A. 6
B. 10
C. 4
D. 11

1/x-1+3/x-1=1
x is -1.333

Iam assuming 3 is part of the question, whenever a number is next to parenthesis it means to multiple, but we do the parenthesis first, so it would be -10 in the parenthesis then you times that by 3, which would be -30.
