kiruha [24]

Answer:

\frac{1}{4} of the books in the book store are mystery fiction books.

Step-by-step explanation:

Let x represent all the books in the books store.

If P(x) = x ^ 2 + x + 3 and Q(x) = 4x ^ 2 - 3 find P(8) .
lara [203]

Answer:

75

Step-by-step explanation:

Giving Q was not necessary because you aren't doing P(Q) or anything like that....

Anyways,

p(x) = x^2 + x +3\\

Since you're doing p(8), you would replace the x's with 8s.

(8)^2 + (8)  + 3 = 64 + 8 + 3 =75

So your final answer would be 75.
