7 is the answer because de is parallel to xy.
Step-by-step explanation:
the picture isn't realistic but mathematically it's:
1) = 121°
2) = 59°
Step-by-step explanation:
perimeter=2(l+b)
18=2[(x+2)+x]
18=2(x+x+2)
18=2(2x+2)
18=4x+4
collecting like terms
18+4=4x
22=4x
dividing by 4
22/4=x
5²/4=5½
V=number of videos, x=total amount
10v*3=x
Since each video is $10, you would have to multiply that by the number of videos. Once you find that you would multiply that number by three, since you will be keeping the videos for 3 days. With that you will find, x, the total amount.
