Was the 12 of GF given??
The area ratio should be 1:4, so if l×w = area (a) of DEFG, then L×W = Area (A) of WXYZ.
Since 4:1 is 4×1, A = 4×a or 4a
Since GF is length (l) and is 12, we can say that 12w = a
12×4 = 48 for length of ZY (L), and WX is also 48, and to find W would be: 48W = A
48W = 4a, since A=4a
Not sure what else you want by the limited information given!
-5, because subtracting a negative is the same as adding a positive, which will bring -9 up to -5

Answer:
-17
Step-by-step explanation:
Solving for y, we find ...
-11y -4 = 7
-11y = 11 . . . . . . . add 4
y = -1 . . . . . . . . . divide by -11
Then the expression of interest has the value ...
9y -8 = 9(-1) -8 = -9 -8
9y -8 = -17
