F(x) = \sqrt(x)
g(x) = 2\sqrt(x)
(f-g)(x) = \sqrt(x) - 2\sqrt(x)
(f-g)(144) = \sqrt(144) - 2\sqrt(144)
(f-g)(144) = 12 - 24
(f-g)(144) = -12
Answer: the answer would be 66
Step-by-step explanation:
Answer:
5 blue marbles
10 Red marbles
3 Green marbles
Step-by-step explanation:
5 times 2 = 10
then 5-2 =3
Add 5+10+3
=18 Marbles in total
<span>(1 gallon)/(20 miles) = (x gallons)/(180 miles)
1/20 = x/180
1*180 = 20x
180 = 20x
20x = 180
</span><span>x = 180/20
x = 9
It takes 9 gallons of gas to drive 180 miles
(9 gallons)*(3.98 dollars/1 gallon) = 9*3.98 dollars = 35.82
Round to the nearest dollar: 35.82 ---> 36
It costs $36 to travel 180 miles</span>
