Answer:
3>b
Step-by-step explanation:
a+b>-4
a>-9
so a is greater than -9
so which means -7,-8,-6 is greater -9.
-7+b>-4
-7+4>-b
-3>-b
3>b
verification
a+b>-4
Substitute -7 for a
substitute 3 for b
-7+3>-4
the answer will be -4 which is correct.
Exactly the same three sides and
exactly the same three angles
Answer:
Must add: 202
Step-by-step explanation:

a = x
2ab = 26x
2ab = 26a [ substitute a instead of x]

b= 13
So,

But given equation is :

We have find the difference between 169 and -33 to get the number that should be added to get the perfect square.
That is , 169 - (-33) = 202
Therefore ,
