Consider solving the equation below for x. 2(4x+1)-3=ax+b
Which statements are true about the solution to the equation when substituting the given values for a and b? Choose all that apply.

If a = 8 and b = 1, then there is no solution to the equation.

B
If a = 4 and b = -2, then there is no solution to the equation.

C
If a = 8 and b = -1, then there is exactly one solution to the equation.

D
If a = 2 and b = -1, then there is exactly one solution to the equation.

E
If a = 2 and b = 4, then there are infinitely many solutions to the equation.

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 )
