<h2>
19 X 33 = 627,  justified.</h2>
Step-by-step explanation:
We have,
19 × 33 = 627
Use the fact and justify.
L.H.S. = 19 × 33
= (20 - 1) (20 + 13)
Using the identity,
(x - a)(x + b) =  - (a - b)x - ab
 - (a - b)x - ab
Here, x = 20, a = 1 and b = 13
=  - (1 - 13)20 - 1(13)
 - (1 - 13)20 - 1(13)
= 400 - (- 12)20 - 13
= 400 + 240 - 13
= 640 - 13
= 627
= R.H.S., justified.
Thus,  19 X 33 = 627,  justified.
 
        
        
        
By looking at ur answer choices, I am assuming the width is 2/5 inches and the length is 3/5 inches.
A = L * W
A = 3/5 * 2/5
A = 6/25 in^2 <==

(x-1)^2 is the factored version, so vertex is at 0, which is 1, so, A
