d = 2√113 ≈23.28

Step-by-step explanation:

$d_{AB}=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\\\d_{AB}=\sqrt{(6+8)^2+(-9-7)^2}=\sqrt{14^2+(-16)^2}=\sqrt{196+256}=\\\\=\sqrt{542}=2\sqrt{113}\approx23.28$

Step-by-step explanation:

Pigment in A + Pigment in B = Pigment in mixture

0.10 (4) + x (10) = 0.35 (4 + 10)

0.4 + 10x = 4.9

10x = 4.5

x = 0.45

Ink B contains 45% blue pigment.
