How do yousolve for x 3x^2 + 14x = -8

Step 1: Subtract -8 from both sides.
3x^2+14x-(-8)=-8(-8)

Step 2: Factor left side of the equation
(3x+2)(x+4)=0

Step 3: Set factors equal to 0.
3x+2=0 or x+4=0

x=-2/3 or x=-4

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 )
