Answer:
x = 7
Step-by-step explanation:
The proportion is
14/6 = 21/(3x - 12) Cross Multiply
14*(3x - 12) = 6*21 Remove the brackets and combine
42x - 168 = 126 Add 168 to both sides
42x = 126 + 168
42x = 294 Divide by 42
x = 294/42
x = 7
Hi there!
Answer:
length = 9 kilometres
Width = 12 kilometres
Let's solve this problem step by step!
To find our answer we need to set up and solve an equation.
Let the length of the rectangle be represented by x.
The width of the rectangle can therefore be expressed by 2x - 6.
The area of a rectangle can be found by using the formula:
A = width × length
Plug in the data from the formula
A = x (2x - 6).
Simplify using rainbow technique.

Now we've found the simplified expression that expresses the area of the rectangle. Therefore, we can now set up and start solve the equation.

Subtract 108

Divide by 2.


Rule AB = 0, gives A is 0 or B is 0.

The length of the rectangle, which was represented by x, must be 9 (since it cannot be a negative number).
Length

Width

Answer:
length = 9 kilometres
Width = 12 kilometres

Answer:
24sq.ft
Step-by-step explanation:
<h3>
Area of a parallelogram = Base*Height</h3>
Here,
→Base = 6ft, Height = 4ft
→ 6*4ft
→24sq.ft
<h3 /><h3>
While writing area of a figure, we have to express the area in sq which means square</h3>
