Rhett decides to build a square room for his movie and music collection. if the area of the room is 9x2 − 6x + 1 square feet, what is the length of one side of the room?

a) (3x + 1) feet
b) (9x − 1) feet
c) (3x − 1) feet
d) (9x + 1) feet

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 )

Hold on lemme do the work
