No because the perfect trinomial has a square as the third term and the middle term is a multiple of 2.
Answer:
For the first page (doesn't show the number), it is the third option.

For the third page or number 15, it is the second option
For the fourth page or number 12, it is the second option
For the fifth page or number 11, it is the second option

Answer:
-3x^2+6x-157
Step-by-step explanation:
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
Answer:
24
Step-by-step explanation
The question just ask to subtract 18 from 42 which would = 24.
