For this case we have the following polynomial:
The standard form of the polynomial is given by:
Where, the axis of symmetry of the polynomial is given by the expression:
}
In this case we have:
Therefore, replacing values we have:
Rewriting we have:
Answer:
The symmetry axis of the polynomial is given by:
option C
Answer:
x^2 - 64
Step-by-step explanation:
A difference of squares is a special product in the form (a^2 - b^2)..their factored form is (a - b)(a + b)..
Thus here a = x and b = 8, thus if x + 8 is a factor, then x - 8 is also a factor..
(x + 8)(x - 8) <-- expand this out using difference of squares rules..
= (x)^2 - (8)^2
= x^2 - 64 <-- answer...
You could also expand that using FOIL (FOIL - first, outer, inner, last)..
(x + 8)(x - 8)
= (x)(x) + (x)(-8) + (8)(x) + (8)(-8)
= x^2 - 8x + 8x - 64 <-- the -8x and 8x cancels out..leaving you with..
= x^2 - 64
I believe C/12=pi which means the answer would be B.
The answer would be 15 but i am not sure what the problem says her answer is. if it is not 15 then her answer is wrong
2/9=2.50
Allowence=2.50x9 divided by which gives you an answer of 11.25
Hope this helps you!
