According to the fundemintal counting princable the answer is 18.
The answer is 19 all you have to do is add them together
7(x + 9 ) - x
Explanation:
the quantity x plus 9 is written x + 9 , plus meaning add.
times the quantity means multiply the quantity x + 9 multiplied by 7
this is written 7(x + 9 )
finally minus x means subtract x
putting it all 'together' we get 7(x + 9 ) - x
Your answer would be 9.1%
(x-5)(x+4) is the factored version of this trinomial so if either of those values in the parenthesis are in the answer bank, choose those.
