Answer:
(x - 7)² + (y + 2)² = (2√13)²
Step-by-step explanation:
We already know that the center is at (7, -2), but must find the radius. The radius is the distance between the points (7, -2) and (1, -6):
r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.
Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²
Answer:
12a+60 i think lol
Step-by-step explanation:
this is how i did it though:
12(a+b)
12a+60
1. is 9
and the other ones i dont really know
Use the Foil Method:
First: t x t =t^2
Outsides: t x 8 = 8t
Insides: -1 x t = - t
Lasts: 8 x -1 = -8
so you'll have t^2 + 8t - t - 8, simplify it more: t^2 + 7t - 8, A.
