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

Feliz [49]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

If the factored form is given by

$(3x-4)(x+2)$

Then its standard form will be given by

$(3x-4)(x+2)\\\\=3x^2+6x-4x+8\\\\=3x^2+2x+8$

if factored form is given by

$(3x+2)(x+4)$

Then its standard form will be given by

$(3x+2)(x+4)\\\\=3x^2+12x+2x+8\\\\=3x^2+14x+8$

Hence, only first option is correct.
