Answer:
The array has 9 rows and 18 columns.
Step-by-step explanation:
Let the number of rows of the array = x
Then, the number of columns = 2x
The division sentence that describes this situation is:
[tex]\frac{2x}{2} =x[/tex]
Here, the dividend is 2x.
But, it is given that the dividend is 18.
So, 2x = 18 and
[tex]\frac{2x}{2} =\frac{18}{2}[/tex]
x = 9
Hence, the array has 9 rows and 18 columns.
