You rearrange the equation to y=5x-2 and the slope is 5 and the Y-intercept is -2 or (0,-2)
X^2 + 9 + 7 = 20
X^2 +16 = 20
X^2 = 20-16
X^2 = 4
Root 4 = 2
X=2
Tangents to a circle from the same point are equal length. Thus, for example, the two segments at the upper left (to A and to D) are both length 4. The ones at lower left are both length 6.
Then
x = 4+6
x = 10
The perimeter is twice the sum of the lengths shown, so is
perimeter = 2(4 + 8 + 3 + 6)
perimeter = 42
