Answer:
-3.5,-0.2,0.6,5 ... is the answer
Answer:
a = 3
Step-by-step explanation:
The triangles are similar, so the ratio of short side to long side is the same for each:
(a +5)/12 = 12/18
a +5 = 12(12/18) = 8 . . . . . multiply by 12
a = 3 . . . . . . subtract 5
The top box is 55%
the second box is 7.35 in pretty sure
8*2*5= 80 because volume= length*width*height
