2x+2y=52
x*y=120
Step-by-step explanation:
The possible lengths of a side of the rectangle are 22, 21, 20, 19, 18, 17, 16 feet.
To find the possible lengths of a side of the rectangle, let's use the formula for the perimeter of a rectangle, which is 2(length + width). We can set up an equation using the given information:
2(length + width) = 52
Dividing both sides by 2, we get:
length + width = 26
Now, to find the possible lengths, we need to consider the area. The formula for the area of a rectangle is length x width. We are given that the area is not to exceed 120 square feet, so we can set up the inequality:
length x width <= 120
Using the relationship length + width = 26, we can substitute length = 26 - width into the inequality:
(26 - width) x width <= 120
Simplifying the inequality, we get:
-width^2 + 26width - 120 <= 0
Now, we can solve this quadratic inequality to find the range of possible widths. Once we have the widths, we can substitute them back into the equation length + width = 26 to find the corresponding lengths.
By solving the quadratic inequality, we find that the possible widths are 4 <= width <= 10. Substituting these widths back into the equation length + width = 26, we get the corresponding lengths:
If width = 4, then length = 22
If width = 5, then length = 21
If width = 6, then length = 20
If width = 7, then length = 19
If width = 8, then length = 18
If width = 9, then length = 17
If width = 10, then length = 16
The possible lengths of a side of the rectangle are {22, 21, 20, 19, 18, 17, 16} feet.

Answer:
a = 60
Step-by-step explanation:
Since it is a quadrilateral, the sum of interior angles is equal to 360°. Now you have to create an equation to solve this question. To create an equation, you have to add all the interior angles to 360°.
The equation would be 2a°+a°+a°+2a° = 360°.
Then you would simplify it to 6a° = 360.
You would divide 6 on both sides to get to a° = 60.
Therefore, the value of a is 60.

The first courier service cost is;
Where, x is the number of kilograms delivered;
The second courier service cost is;
Equating it, we have;
Thus, the weight that will result in equal cost is 1 kilogram.
And the cost is 5( 1 )+14 = $19

-3 x + 1/2 V = -3
Answer:
-6
Step-by-step explanation:
V = 6x + b
1/2 V -3 x = -3
V - 6x = -6
V - 6x = b
