Answer:
The width is 7 meters and the length is 13 meters
Step-by-step explanation:
The perimeter of a rectangle sandpit is 40 meters.
Let the width be w units, then the length which is 1 meter less than twice it’s width becomes: 
The perimeter of a rectangle is given by:

We substitute P=40 and the length in term of w to get:

We simplify to get:

Divide through by 2 to get:
Hence 
Answer:
x² - 9
Step-by-step explanation:
(x + 3)(x - 3)
= x(x - 3) + 3(x - 3) Distributive property
= x² - 3x + 3x - 9
= x² +( -3x + 3x) - 9 Associative
= x² + 0x - 9 Addition
= x² - 9
