–3(c + 14) + 3 = 15 solve for c

c = -18

Step-by-step explanation:

–3(c + 14) + 3 = 15

⇔

–3c - 42 + 3 = 15

⇔

-3c = 15 + 42 - 3

⇔

-3c = 54

⇔

c = - 54/3

⇔

c = -18

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 )
