Answer:

Explanation:
The volume of a rectangular box is given by;

It was given that, the volume of the box is V=8 cubic inches.
The length of the box is l=2 inches.
Let the width of the box be x inches.
The height of the box is 3 inches more than the width. That is

We now substitute all values into the formula to get:

Therefore the required equation is

Answer:
Amount to spend = $18.50
Purchased banana =$1.50
Apple Juice =$1.55
Gasoline $2.35
$1.50 + $1.55 = $3.05
18.50 - 3.05 = 15.45
1 Gallon of Gasoline = 2.35
Therefore,
2.35 x 6 = 14.1
15.35 - 14.1 = 1.25
To avoid exceeding budget, he can only buy
6 gallons of gasoline
G(k) = 67
f(5) = (5)^2 - 18 = 25 - 18 = 7.
g(k) = g(7)
g(7) = (7)^2 + 18 = 49 + 18 = 67.
hope this helps
