2x + 20
Explanation:Given:
[tex]2(x\text{ + 10\rparen}[/tex]To find:
To use a rectangular array to write the products in standard form
To use a rectangular array for the product, we will construct rectangles representing x and 10:
Next, we will multiply the expression outside by 2. The results will be in each box
The product in standard form will be the sum of each expression in the box = 2x + 20
[tex]2(x\text{ + 10\rparen = 2x + 20}[/tex]
