Answer:
a2 + 2al (or) a2 + √a24+h2 a 2 4 + h 2
Step-by-step explanation:
Distance Formula: 
Point 1: (9,0)
Point 2: (5,-8)
D = sqrt[ (5 - 9)^2 + (-8 - 0)^2 ]
D = sqrt[ (-4)^2 + (-8)^2 ]
D = sqrt[ 16 + 64]
D = sqrt(80)
Hope this helps!
1) $450/12=$37.50
2)$37.50x3=$112.50
The answer is: $112.50

If b>a, b-a=5 so b=5+a
ab=126, using b from above
a(5+a)=126
5a+a^2=126
a^2+5a-126=0
(a+14)(a-9)=0, since a<0 the numbers are
-14 and -9
