Answer: x=3
Step by Step:
(x+2)2+(y-3)2=4
2x+4+(0-3)x2=4
2x+4-3x2=4
2x+4-6=0
2x=6
x=3
The dimensions of the rectangle would be (6-2) x (7-0) = 4 x 7
That makes the area (4)(7) = 28.
That makes the perimeter (7+4)(2) = 22
That makes the diagonal sqrt((7^2)+(4^2)) = sqrt(49+16) = sqrt(65)
Axis -b/2a=-12/2*3=-2
vertex(-2,-3)
6x+3y=15
-6x. + -6x
3y=-6x+15
÷3 ÷3 ÷3
y=-2x+5
m=-2/1
b=5
