What is the product of (-2x)(-6x^4)?

12x^5

Step-by-step explanation:

(-2x)(-6x^4)

Multiply the numbers

-2 * -6 = 12

Multiply the variables

x* x^4 = x^5

12x^5

∠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°

47 - 90 = 43

43 - 180 = x

x = 137
