Answer:
x = 1.35
Step-by-step explanation:
Circle equation is x^2 + y^2 = 13.
Plug y = x + 2 in the circle equation:
x^2 + (x + 2)^2 = 13
x^2 + x^2 + 4x + 4 = 13
2x^2 + 4x - 9 = 0
x = [-4 +/- sqrt(4^2 - 4*2*-9) ] / 2*2
= -1 +/- [sqrt(88 )] / 4
= -3.35. 1.35

Answer:
c. 12
Step-by-step explanation:
PA² = (BC + PB) × PB => tangent-secant theorem
PA = 8
PB = 4
BC = ?
Substitute
8² = (BC + 4) × 4
64 = 4BC + 16
64 - 16 = 4BC + 16 - 16
48 = 4BC
48/4 = 4BC/4
12 = BC
BC = 12
