just look up circumference of a circle and you should be able to put the radius in the first thing that pops up :)
Hi there!
Pauline simplified the expression correctly.
Pauline made sure she used the distributive property and combined like terms after doing so.
Hope this helps !

Answer:
A = 1/4
B = 3/4
step-by-step explanation:
the middle should be 1/2 because the middle between 0 and 1 is 1/2
A and B are both in the middle of the sides
therefore A would be closer to 0 so 1/4
and B would be closer to 1 so 3/4
Answer:
23) x= 3, y = 4
24) Any (x,y) values where x = 1.5 - 2y
Step-by-step explanation:
For the first system(23), it goes like this
[1 2 | 7]
[2 1 | 8]
We need to do L2 = L2 - 2L1, so now it is
[1 2 | 7]
[0 -3 |-6]
So, now we have:
-3y = -6 *(-1)
3y = 6
y = 2
x + 2y = 7
x + 4 = 7
x = 3
Now for system 24, we have:
[-1 2 | 1.5]
[2 -4| 3]
We do L2 = L2 + 2L1, so we have:
[-1 2 | 1.5]
[0 0| 0]
So there are infinite solutions for this system. The solution for this system will be each (x,y) pair where x = 1.5 - 2y.
