ax² + bx + c = 0
You know:
a = -2
b = 1
c = 3
The 1st option is your answer
-2x² + x + 3 = 0
a = -2
b = 1
c = 3
<em>THE ANSWER IS 110 m</em>
<em>Workers had repaired 3/4 of the road</em>
<em> it means3/4×440 is been repaired</em>
<em>length of repaired road is 3×110 = 330m</em>
<em>length of unrepaired road = Length of to road - length of repaired road</em>
<em>i.e. = 440-330 = 110m</em>

Answer:
<h3>6 degrees</h3>
Step-by-step explanation
Find the diagram attached. In Line geometry, there is a theorem that states that the sum of the adjacent interior angles is 180 degrees. According to the diagram, the adjacent interior angles are 7x- 15 and 24x + 9.
The sum of this angles must give 180 degrees as shown;
7x-15 + 24x + 9 = 180
7x+24x-15+9 = 180
31x-6 = 180
31x = 180+6
31x = 186
x = 186/31
x = 6
Hence the value of x is 6 degrees
