Which of the following is a factor of x2 + 20x + 96? a) x + 4 b) x + 6 c) x + 3 d) none of the above

D) None of the above

Step-by-step explanation:

We are given the following expression and we are to factorize it:

Finding factors of 96 such that they give a product of 96 when they are multiplied and 20 when they are added:

=

=

=

So the two factors of the given quadratic expression are (x + 12) and (x + 8). But these are not present in the given answer options so the correct option is D) None of the above.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
