Answer:
3/2
I hope this is correct
3/2 = 1.5
Step-by-step explanation:
Find two corresponding sides whose lengths are given.
AB and WX
The scale factor from quad ABCD to quad WXYZ is the ratio of a length in WXYZ to the corresponding length in ABCD.
scale factor = 12/8 = 3/2 = 1.5
67.50
The Answer is 9
see below
m/3 + 4 = 7
Subtract 4 from each side
m/3+4-4 = 7-4
m/3 = 3
Multiply each side by 3
m/3*3 = 3*3
m =9
