Question

- The length of Christina's table is the product of 4 and X. The width of her table is 2 less

than twice the length. What is the perimeter of her table?

Answer 1

24x - 4

Explanation:

Perimeter of a table = 2(length + width)

length of Christina's table is the product of 4 and X

Length = 4x

The width of her table is 2 less

than twice the length.

Width = 2(4x) - 2

= 8x - 2

Perimeter of a table = 2(length + width)

= 2{4x + (8x - 2)}

= 2(4x + 8x - 2)

= 2(12x - 2)

= 24x - 4

Perimeter of a table = 24x - 4
