Hey there!
To find the opposite of a number, you switch its sign, and to do so, you would multiply by -1. This gives us the equation below.
n=-n+96
To find our number, we need to isolate all of our n's on one side of the equation. Let's try adding n to both sides.
2n=96
We divide both sides by 2.
n=48
As you can see, the opposite of 48 is -48, and 48 is 96 more than -48.
Therefore, our number is 48.
I hope this helps!
The first one.. this is the definition of symmetry
There is 4 X so you use 360- (11+1) which is 348 and now divide by 4 which is now 87

Answer:
(a) 
(b) 
Step-by-step explanation:
(a) Write and simplify an expression for the exact area of the sidewalk.
(b) Find the approximate area of the sidewalk. Use 3.14 to approximate .
(a) The sidewalk area is the difference in the area of outer circle and inner circle.
Use formula 
for the area of the circle:
The difference is
(b) Use approximation 
then
Is it 25 or no I guess it’s not
