The first answer is 2.5 and I don’t know the last two sorry
The determinant is found by the formula ad-cb
where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0
12x2 = 24
-6x0 =0
24-0 = 24
the determinant = 24
Answer:
D. Linear, because the function increases by a common difference
Step-by-step explanation:
Since it is increasing always at the same rate it is linear.

Answer:
a = (-7)
Step-by-step explanation:
Firstly clear the bracket...,
-6(-2 + a) = 12 - 6a
Then substitute the simplified version in place of bracket...,
; 12 - 6a = 54
; -6a = 54 - 12
; -6a = 42...then divide both sides by (-6)
Therefore...., a = (-7)
(3x + 14) (3x + 14) = 9x^2 + 24x + 16
