Answer:

The factors are 3 and -9

Step-by-step explanation:

The given trinomial is x^2-6x-27.

We need to find two factors. We know that,

3(9) = 27

So,

x^2-6x-27 can be written as :

x^2+3x-9x-27 as two factors add up to get -6 and multiply to get -27.

Hence, the factors are 3 and -9.

Step-by-step explanation:

From the diagram, we can see that the angle measures and side measures of figures 1, 3 and 4 are the same.  This means that these three figures are congruent.  Figure 2, however, is not congruent to any of the other 3.
