What is the product of 6x – y and 2x – y + 2? A=8x2 – 4xy + 12x + y2 – 2y B=12x2 – 8xy + 12x + y2 – 2y C=8x2 + 4xy + 4x + y2 – 2y D=12x2 + 8xy + 4x + y2 + 2y

Should be Product of two expression is (6x-y)(2x-y)=12x^2-8xy+y^2

B: 12x^2-8xy+12x+y^2-2y

Step-by-step explanation:

(6x-y)*(2x-y+2)

12x^2-6xy+12x-2xy+y^2-2y

12x^2+y^2+12x-2y-8xy

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
