Step-by-step explanation:
I'm pretty sure that's the correct answer..
Answer:
D
Step-by-step explanation:
We are given that the side of a square is: 8√12.
And we want to find the area.
The area of a square is given by:
Where <em>s </em>is the side length. Remember that all side lengths in a square are equivalent.
Therefore, by substitution, we acquire:
Evaluate. We can expand:
Simplify:
Hence, our final answer is D.
Answer:
B. x=-6 or x=8
Step-by-step explanation:
To solve this, factor the equation x^2-2x-48. Since -48 is negative, one of the factors has to be negative and one has to be positive. Since the coefficient of x is -2, the factors have to sum to -2. Trying factors, we realize that (x-8)(x+6)=0 works. Solving, x-8=0 and x+6=0, or x=8 or x=-6.
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
