Which expression is equivalent to 6(2-3x)?

A) 12-18x
B) 12-9x
C) 8-18x
D) 8-9x

A by the use of the distributive property

The answer is A) 12-18x. This is the answer because when you distribute the 6, you get 12-18x.

∠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°
