Answer:
68 feet square
Step-by-step explanation:
The rectangle with the maximum area for a given perimeter is a square. The perimeter of a square is 4 times the side length, so the side length of the square area will be ...
(272 ft)/4 = 68 ft
_____
<em>More formally ...</em>
You can let x represent the length of one side. Then the length of the other side for the given perimeter will be 136 -x, and the area will be the product ...
area = x(136 -x)
The area function is a quadratic with zeros at x=0 and x=136. The vertex (maximum area) will be at the value of x that is on the line of symmetry between these points, at their midpoint: x = (0 +136)/2 = 68. This value of x makes the rectangle a square.
Answer:
112 ounces
Step-by-step explanation:
Malia bought 14 cans of cat food
Each of the can weighs 8 ounces
Therefore the total ounces of cat food bought can be calculated as follows
= 14×8
= 112 ounces
| -6x - 3 | > 15
This expression can be written as:
a) -6x - 3 > 15
b) -15 > - 6x - 3
Solving a part:
Solving b part:
or we can write:
x > 2
So the solution to given inequality is:

The second option correctly lists this solution.
