We make use of the special form for the difference of squares:
(a+b)(a-b) = a²-b²
Answer:
120
Step-by-step explanation:
The area of a rectangle is its width multiplied by its length, which in this case is 12*10=120.
Expanded form is when you just write it out.
so 9 cubed becomes:
9×9×9
and 20 squared becomes:
20×20
the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.
