-4x^2-5x-15+x^2= -3x^2-5x-15 is the answer
Answer:
(x - 7)^2 + (y - 2)^2 = 5^2
Step-by-step explanation:
Center at (7, 2); radius 5
Adapt (x - h)^2 + (y - k)^2 = r^2 to this situation. Replace h by 7, k by 2 and r by 5:
(x - 7)^2 + (y - 2)^2 = 5^2
Answer:
25
Step-by-step explanation:
it's because 5 is squared so 5x5 is 25 and x squared
