I think the answer is D
Hope it helps
6,000.000+800.000+50.000+8.000+0.000+0.20+0.6
40%= 0.40 if you think of the decimal being at the end of the number (40.%) than just move the decimal twice makes it 0.40
w + 4

l l

Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w
Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds
1.Simplify/combine like terms:
w + 4 + w + w + 4 + w =
4w + 8 =
Now it's a 2-step algebra equation
4w + 8 = 60
2.Subtract 8 on both sides
4w = 56
3.Divide both sides by 4
w = 14
