Can anybody help me with this please??
Verizon [17]

Answer:

x = 5

Step-by-step explanation:

\frac{10}{x} = \frac{14 + 10}{2x - 3 + x}

\frac{10}{x}  = \frac{24}{3x - 3}

24 x = 10 . (3x - 3)

24x = 30 x - 30 \\6x = 30 \\x = 5

The entire large rectangle above is 38 units long and 2 units wide.
Its area is length times width, so the area is 2 * 38.
38 is also the same as 30 + 8, so the area can also be written as 2(30 + 8).

The left rectangle is 30 units long and 2 units wide. Its area is 2 * 30.
The right rectangle is 2 units long and 8 units wide. Its area is 2 * 8.

If you add the areas of the small rectangles, you get
2 * 30 + 2 * 8

If you add the two small areas, you get the area of the laerge rectangle, so

2(30 + 8) = 2 * 30 + 2 * 8

which is an example of the distributive property.
