Answer:
x = 8
Step-by-step explanation:
By first drawing a photo, pasted below, you can plot your points. Then use the formula:
a/c = b/d to plan out your equation
3x - 8/x = 16/x
Cross multiply so you then have:
16x = 3x^2 - 8x
24x = 3x^2
8 = x
To check:
3(8) - 8 = 16
24 - 8 = 16
16 = 16
The line <em>AC</em> is a side that is common to both triangles.

Answer:
x = 32
Step-by-step explanation:
x - 7 = 25
To solve equations, you do the some thing to both sides to isolate x.
After adding 7 to both sides we have:
x = 32
The perimeter of the rectangle is the sum of its dimensions
The dimensions that minimize the perimeter are 
The area is given as:

Let the dimension be x and y.
So, we have:

Make x the subject

The perimeter is calculated as:

Substitute 

Expand

Differentiate

Set to 0

Rewrite as:

Divide both sides by -1

Multiply y^2

Divide by 2

Take square roots of both sides


Substitute
in 



Hence, the dimensions that minimize the perimeter are
