Ineed asap find the value of the expression 3(4x − 4y), when x = 3 and y = 2.

Math it's appreciated. (picture provided)

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142

Use sigma notation to represent the following series for 9 terms.
