Answer:
A) 
Step-by-step explanation:
Given expression:
To factor the given expression completely.
Solution:
In order to factor the expression, we will factor in pairs.
We will factor the G.C.F of the terms in the pairs.
G.C.F. of 
and 
can be given as:
Thus, G.C.F. = 
G.C.F. of 
and 
can be given as:
Thus, G.C.F. = 
The expression after factoring the G.C.F. pairs is given as:
Taking G.C.F. of the whole expression as 
is a common term.
The expression is completely factored.
Answer:
Step-by-step explanation:
you do 10/2 for the radius, so that will be 5. then you do 3.14*5*5= 78.5
Thats gonna be region A.
lets check...this point is in that region (-1,3)
now we sub into our equations and see if it is true
y < = -5/2x + 4 y > = -1/2x - 2
3 < = -5/2(-1) + 4 3 > = -1/2(-1) - 2
3 < = 5/2 + 4 3 > = 1/2 - 2
3 < = 5/2 + 8/2 3 > = 1/2 - 4/2
3 < = 13/2 3 > = - 3/2
3 < = 6 1/2...true 3 > = - 1 1/2...true
so it is region A...100% sure
