Solve - 2x = 8 question 1 options: a. -4 b. 10 c. 6 d. -16

- 2x = 8 

Means that you divide both sides by -2 to get the x by its self...

x = -4

To check... Just plug in the value for x..

-2 ( -4 ) = 8 

So the answer for this question is -4 ( A)

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
