Answer:
B 12.68
Step-by-step explanation:
you will need to find the distance between each segment-
so the length of DC, CF, FE, ED

DC:
D(-2,-1) C(-1,2)

CF:
C(-1,2) F(1,1)

FE
F(1,1) E(2,-2)

ED
E(2,-2) D(-2,-1)

3.16+2.24+3.16+4.12= 12.68
931 are the answer ................
Answer: 8 oz..
1 pound= 16oz if 8oz=1.59 so add it up 4 times 8+8+8+8= 32 which = 2 pounds total 8=1.59 8+8= 1.59x2=3.18 8+8+8=1.59x3=4.77 8+8+8+8/ 1.59x4= 6.36 so all of them eights will = up to 2 pounds and 8 is obviously less
