Which of the following is a true statement about perfect squares? 8 - 8 = 16 ,13 - 13 = 2(13) 81 is a perfect square. 111 is a perfect square.

Step-by-step explanation:

Given the following conditions

step one:

1.    8 - 8 = 16 which amounts to false

8-8=0

step two:

2.   13 - 13 = 2(13) which is also false

13 - 13 = 26

13-13=0

step three:

3. 81 is a perfect square

we can check to verify

√81=9 which is correct hence true

step four:

4. 111 is a perfect square

√111=10.53 which is incorrect

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
