Answer:
-361
Step-by-step explanation:
Your calculator can tell you the result. It is -361.
Start with the inner parentheses and work outward. Do multiplication and division in the order shown, left to right, before addition or subtraction.
-3[2/6+8{-9/3(8-5*3)-6}]
= -3[2/6+8{-9/3(8-15)-6}]
= -3[2/6+8{-9/3(-7)-6}]
= -3[2/6+8{-3(-7)-6}]
= -3[2/6+8{21-6}]
= -3[2/6+8{15}]
= -3[1/3+8{15}]
= -3[1/3+120]
= -3[361/3]
= -361
Answer:
The length of the fence that encloses the park is 400 m
Step-by-step explanation:
step 1
Find the length of the square city park
we know that
The area of a square is
where
b is the length side of the square
we have
substitute and solve for b
take square root both sides
step 2
Find out the length of the fence that encloses the park
we know that
The length of the fence is equal to the perimeter of the square city park
The perimeter of the square is
we have
substitute
therefore
The length of the fence that encloses the park is 400 m
