So factor out the 5
5(n^2+2n+4)
this cannot be simplified unless you use quadratic formula and the answer is non-real

Answer:
B
Step-by-step explanation:
Since r and s are parallel lines, then
The angle adjacent to 1 is corresponding to 158 and are congruent, thus
adjacent angle to 1 = 158°
1 and 158° are adjacent and supplementary, so
∠ 1 + 158° = 180° ( subtract 158° from both sides )
∠ 1 = 22° → B
1/2 tried to cross the road.....3/4 made it..
3/4 of 1/2 = 3/4 * 1/2 = 3/8...so 3/8 made it to the other side
