The answer should be 390 because you multiply all the numbers because area is length x width x height
<span>X^2+x-2/1-x^2 ÷ 2x^2-6x-20/x^2-4x-5
(x + 2)(x - 1) (x - 5)(x + 1)
= ------------------- * ---------------------
(1 + x)(1- x) 2(x + 2)(x - 5)
</span> (x - 1)
= ----------
2(1- x)
- (1 - x)
= -------------
2(1 - x)
= -1/2
answer
-1/2
If the digit of 0 is allowed, then:
1/(10*9*8)= 1/720
If it is not permitted, then:
1/(9*8*7)= 1/504
I hope this helps you!
