The answer is Always true. because A is greater than B so put it this way if A=2 and B =1 then 2>1 same goes for C>D so if A+C would have to be greater than B+D for instance 2+2>1+1 or 4>2 so
<span>If A>B and C>D, then A+C>B+D Always true.

1/10 is the probability.
You find this by putting 25/250 and simplifying.
Answer:
(x-2)^2 +(y+3)^2 = 16
Step-by-step explanation:
The equation of a circle can be written as
(x-h)^2 +(y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-2)^2 +(y- -3)^2 = 4^2
(x-2)^2 +(y+3)^2 = 16
Answer:
C) 
Step-by-step explanation:
The given expression is

We rewrite to obtain:

Multiply the first fraction by the reciprocal of the second to get;

Factor the numerator using difference two squares;


Cancel out the common factors to get;

This simplifies to;
