The polynomial that represents the perimeter of the rectangle is P = 6x + 16y
<h3>What are perimeters?</h3>
The perimeter of a shape is the sum of the side lengths of the shape
For all regular quadrilaterals, you add up the side lengths to determine the perimeter
<h3>How to determine the polynomial that represents the perimeter of the rectangle?</h3>
The given parameters are
Length = 5x + 2y
Width = 6y - 2x
The polynomial that represents the perimeter of the rectangle is represented as
P = 2 * (Length + Width)
Recall that:
Polynomial expressions are mathematical statements that are represented by variables, coefficients and operators
So, we have
P = 2 * (5x + 2y + 6y - 2x)
Evaluate the like terms
So, we have
P = 2 * (3x + 8y )
Open the brackets
P = 6x + 16y
Hence, the required polynomial is P = 6x + 16y

Answer:
$2,800 was in the first account while $1,900 was in the second account
Step-by-step explanation:
Here, we want to know the amount of money in each account.
Let the amount in the first account be $x while the amount in the second account be $y
The addition of both gives $4,700
Mathematically;
x + y = 4700 ••••••••(i)
The amount of interest on first account is 14% = 14/100 * x = 14x/100
The amount of interest on second account is 11% = 11/100 * y = 11y/100
So the addition of both gives the total interest;
14x/100 + 11y/100 = 601
Multiply through by 100
14x + 11y = 60100 •••••••(ii)
From i, x = 4700-y
Substitute this into equation ii
14(4700-y) + 11y = 60100
65800 -14y + 11y = 60100
65800 -3y = 60100
3y = 65800 -60100
3y = 5700
y = 5700/3
y = 1900
Recall from substitution x = 4700 -y
x = 4700 -1900
x = 2800
