If f(x + 2) = 6x2 + 5x − 8. Find f(6).

1 answer:

6 0

Answer:

108

Step-by-step explanation:

We can rewrite f(x+2) to make it easier to evaluate:

f(x+2) = (6x +5)x -8

Since we want f(6), we want x+2 = 6, or x=4.

f(6) = (6·4 +5)·4 -8 = 29·4 -8

f(6) = 108

$-\frac{1}{2} *(-\frac{5}{6} )+(-\frac{1}{2} )*\frac{1}{3} \\=\frac{5}{12} -\frac{1}{6} \\=\frac{5}{12} -\frac{2}{12} \\=\frac{3}{12} \\\frac{1}{4}$

Hmm. Try counting the side of the shape and add the sides. Using the sides as numbers you may be able to solve the problem.
