The best answer is (x-2)x(x-7) and by solving it you do
x^2-9x+14
x^2-2x-7x+14
xx(x-2)-7x+14
(X-2)x(x-7)

Answer:

120°

Step-by-step explanation:

Sum of angles = (n-2)180°, where n is the number of sides.

This is a hexagon, so n=6.

Sum of angles = (6-2)180° = 720°

Each interior angle = 720°/6 = 120°

Answer:

35 different selections of soundtracks are possible

Step-by-step explanation:

Total number of soundtracks available at the store = 7

Enny decides to purchase 3 movie soundtracks.

So, in this problem we have to find in how many ways can Enny chose 3 soundtracks out of 7. The order in which the soundtracks are chosen does not matter e.g soundtracks A,B and C are the same as soundtracks B,C and A.

In an arrangement when the order does not matter, we use combinations to find the total possible number of arrangements or selections.

So, for this problem choosing 3 soundtracks out of 7 means forming combinations from 7 objects taken 3 at a time. This can be represented mathematically as:

$^{7}C_{3}$
