Answer:

90

Step-by-step explanation:

10!/(10-2)!

n!=n(n-1)!

10•9•8!/(10-2)!

10•9•8!/8!

The 8! cancels out and you're left with 10•9

So, your answer is 90

Answer:

- 35

Step-by-step explanation:

2(x - 7) = 3(x+7)

2x - 14 = 3x + 21

x = - 35

Rechecking :

2(-35 - 7) = 3 (-35 +7)

- 84 = - 84
