2x - 10 -12x + 6 = 6
-10x -4 = 6
-10x = 10
-x = 1
x = -1
Since the length of this rectangle is twice its breadth, the length is equal to 40 cm.
<h3>How to calculate the area of a rectangle?</h3>
Mathematically, the area of a rectangle can be calculated by using this formula:
Area = Length × Width
Based on the information provided, we have:
- Its length is decreased half of the 10 cm ⇒ (length - 5)
- Its breadth is increased by half of the 10 cm ⇒ (breadth + 5)
- Its area is increased by 75 cm ⇒ (area + 5)
Substituting the parameters into the formula, we have:
LB + 75 = (L - 5)(B + 5)
2B² + 75 = (2B - 5)(2B + 5)
2B² + 75 = 2B(B + 5) - 5(B + 5)
2B² + 75 = 2B² + 10B - 5B - 25
5B = 75 + 25
5B = 100
B = 100/20
B = 20 cm.
For the length, we have:
L = 2B
L = 2 × 20
L = 40 cm.

(165*12)/5*11 = AHW (average hourly wage)
1980/55 = AHW
36 = AHW
$36 is her average hourly wage.
The formula for volume of a sphere is : V= 4/3 * PI * r^3
r = 1/2 the diameter: 14/2 = 7 feet
Volume = 4/3 * 3.14 * 7^3
Volume = 1,436 cubic feet.
