and 72 is D.
Answer:
The function is a growth function so I guess A, B and D
suggest a growth curve
Step-by-step explanation:
Answer:
Step-by-step explanation:
new length=15+x
width=19+x
then area=(15+x)×(19+x)=285+15x+19x+x²=x²+34x+285 ft²
original area=15×19=285 ft²
then 285+98=x²+34x+285
or
x²+34x-98=0
x²+34x+17²=98+17²
(x+17)²=98+289=387
x+17=√387=3√43
x=3√43-17 ft
1 gal = 3.8 liters....so 65 gallons = 65 * 3.8 = 247 liters
