Answer:
(x + 11 ) * ( x - 11)
Step-by-step explanation:
The expression:
x² - 121
is a difference of squares
We notice that √x² = x and √121 = 11
Then
( x² - 121 ) = ( x + 11 ) * ( x - 11 )
If we multiply
( x + 11 ) * ( x - 11 ) = x*x - 11*x + 11*x - (11)*(11)
( x + 11 ) * ( x - 11 ) = x² - 121
That is what we want to probe
Answer: B
Step-by-step explanation:
Since this is a 30-60-90 triangle, b=8(sqrt3) = 8sqrt3.
By the same logic, c=8(2)=16.
