List in ascending order:-
32 39 45 48 50 57 65 68 70
Q1 = (39+45)/2 = 42
Q2 = 50
Q3 = (65+68)/2 = 66.5
Correct option is the first one.
The function is: f ( x ) = x³ - 2 x² - 68 x - 120
If f ( - 2 ) = 0, we have to divide this equation by: ( x + 2 )
( x³ - 2 x² - 68 x - 120 ) : ( x + 2 ) = x² - 4 x - 60
- x³ - 2 x²
--------------
- 4 x² - 68 x - 120
4 x² + 8 x
---------------------------
- 60 x - 120
60 x + 120
-----------------
0
After that for a function: f ( x ) = x² - 4 x - 60; f ( - 6 ) = 0
( x² - 4 x - 60 ) : ( x + 6 ) = x - 10
-x² - 6 x
-----------------
- 10 x - 60
10 x + 60
-------------
0
Answer:
C ) ( x - 10 ) ( x + 2 ) ( x + 6 )

Each hat cost at least $25.92
Triangle JKL has vertices J(−2, 2) , K(−3, −4) , and L(1, −2) .
Rule: (x, y)→(x + 8, y + 1 )
J’ (-2, 2) → (-2 + 8, 2 + 1 ) → (6, 3 )
K’ (-3, -4) → (-3 + 8, -4 + 1 ) → (5, -3 )
L’ (1, -2) → (1 + 8, -2 + 1 ) → (9, -1)
J’ (6,3)
K’ (5,-3)
L’ (9,-1)
Hope this helps!
