The area of a rectangle is obtained through the equation,
A = L x W
The width of the yard is 4 ft less than the length and may be expressed as L - 4. Length may be solved through the following steps,
A = (L)(L-4) ; 96 = L(L - 4) ; L = 12 ft
The length and width are 12 ft and 8 ft, respectively. Perimeter may be solved through the equation,
P = 2 x (L + W)
Substituting the values of L and W
P = 2 x ( 12 ft + 8 ft) = 40 ft
Therefore, the perimeter of the yard is 40 ft.
12, because 4 rows and 3 sections in each
4x3=12
Kevin is incorrect because x+x is adding two numbers, but x^2 is multiply.
Step-by-step explanation:
Given
A container has 19.5 liters of water
A cup can hold 210 ml of water
1 L is equivalent to 1000 ml
So, 19.5 L is equivalent to 
So, the number of requires to hold this much water
92.85 implies 92 full cups and 1 cup which is partially filled. Hence, almost 92 cups can be filled completely.
7x + 5 = 8x - 25
- 5 = -8x -5
-------------------------------
7x - 8x = - 5 - 25
-1x = - 30
----- -------
-1 -1
x = 30
