Divide (x4 – 11x3 – 49x2 + 899x – 2506) ÷ (x – 8).

Okay first make sure you change negative 8 to a positive 8. 
Set the problem up 8  -11 -49 899 -2506
                                   
8  -11 -49   899    -2506
          -88 -1096    -1576
   
    -11 -137 -197     -4082

Your answer will be 
-11x^3 - 137x^2 - 197x - 4082

C. i believe it is (5×(-20))+(100×(0.7))

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 )
