Answer is 4 .............
Answer:
x+y+2=-5 -2x-y+2=-1 x-2y-2=0 solve algebraically
x+y+2=-5 equation 1
-2x-y+2=-1 equation 2
x-2y-2=0 equation 3
Add equation 1 + 2+ 3
x+y+2=-5 + -2x-y+2+1 + x-2y-2
x+y+2= -7+2+1-2x+x+y
x+y+2= -4-x+y
x+y+2+4+x-y= 0
2x+6= 0
2x= -6
divide both side by 2
x= -3
from equation 1 insert x
x+y+2=-5
since x=-3
then, -3+2+y= -5
-1+y= -5
y= -5+1
y= -4

Answer:
the answer is L. or the last answer
Step-by-step explanation:
you have to find the total area of the place first...
which is 21*17=357
then subtract the inner area (white area) which is
14*20=280
do 357-280 to get the remaining area and the answer is 77ft^2
hope this helps.. vote, comment, thanks, and maybe mark me brainliest lol idk
