Answer:
Answer is D
Step-by-step explanation:
Equaton of a circle that is centerd at (h,k) and radius r is
(x-h)²+(y-k)²=r²
center is (-4,9) and radius is 11
(x-(-4))²+(y-9)²=11^2
(x+4)²+(y-9)²=121
I got you! What’s the question
Answer:
Yes, 3(x+1)(x+7)-(2x+5)² is never positive
Step-by-step explanation:
So....
3(x+1)(x+7)-(2x+5)(2x+5)
=3(x²+8x+7)-(4x²+20x+25)
=3x²+24x+21-4x²-20x-25
=-x²+4x-4
