A, because a pre-image means an image before its altered, and VSTU would be the image as a result of DEFG being transformed
It would be 20
21.3
-1.8
------
19.5 rounded would be 20
6 4/5 + 6 4/5 + 2 2/3 + 2 2/3 = 18 14/15
First change the mixed fraction into an improper fraction
7 1/2 = 15/2
Next, change multiply 2 to both numerator and denominator
15 x 2 = 30
2 x 2 = 4
30/4
Each piece needs 3/4 of an inch. Divide 30 with 3
30/3 = 10
c) 10 pieces is your answer
hope this helps
