Answer:
400 feet long
50 feet wide
Step-by-step explanation:
Length = l
Width = w
2l + 2w = 900
l = 8w
Plug the l from the bottom equation into the top equation
2 x 8w+ 2w = 900
16w = 900
Divide both sides by 16
16w/16 = 900/16
w = 50
The width is 50 feet
Now plug the new w into one of the original equations; we'll use the bottom one
l = 8(50)
l = 400
Answer:
b is an equation because it has =
Step-by-step explanation:
x = -5
YQ/SQ = JB/DB
YQ/72 = 60/45
YQ = 72*(60/45) = 96
Selection D is appropriate.
