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
Hello!
-3(x - 14) + 9x = 6x + 42
Distribute the coefficient of the parenthesis:
-3(x) - 3(-14) + 9x = 6x + 42
-3x + 42 + 9x = 6x + 42
Combine like terms:
6x + 42 = 6x + 42
Both sides of the equation are the same, therefore:
There are infinitely many solutions.
Answer:
Bernice would need 6 days assuming that everything remains constant to make $2430.
Step-by-step explanation:
Assuming she sells every single seashell every day.
First, find the total amount she makes per day by multiply the amount she sells them for ($3) with the total amount of sea shells she sells each day ($135):
135 x 3 = $405
Bernice makes $405 each day.
Now, to solve for the amount of days, divide the total amount she wants to make ($2430) with the amount she makes per day ($405):
2430/405 = 6
Bernice would need 6 days assuming that everything remains constant to make $2430.
