Answer:
where is the question???
Step-by-step explanation:
If p(4) = 16 then
n*4² + 8 = 16
16n + 8 = 16
16n = 16 - 8
16n = 8
n = 8/16 = 0.5
If n = 0.5 then
p(-3) = 0.5*(-3)² + 8
p(-3) = 0.5 * 9 + 8
p(-3) = 4.5 + 8
p(-3) = 12.5

2 1/4 miles => 1 week
1 mile => 1 ÷ 9/4
( 9/4 is an improper fraction of 2 1/4 )
12 1/2 miles => ( 1 ÷ 9/4 ) × 25/2
= 50/9
= 5 5/9 weeks
( 25/2 is an improper fraction of 12 1/2 )
Therefore, it will take 5 5/9 weeks for the company to replace the stretch of road.
( you can round it off to 6 weeks if the qn specify to give to the nearest whole number )
