Answer: 115
Step-by-step explanation:
25d^2-30d-35d+42=25d^2-65d+42.
What? That doesn't make sence! Any way if you mean 1997 to 2014 how many years.
Answer:
$1,190
Step-by-step explanation:
$850(0.25) = 212.50
$850(0.15) = 127.50
$850+212.50= 1,062.50
1,062.50+127.50= 1,190
L=w+2 and 2w+2l=40
Substitute length for w+2 in perimeter formula.
2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9
l=w+2
l=9+2
l=11
a=lw=11*9=99 meters
