Answer:
3 . . . goes in both boxes
Step-by-step explanation:
Use the distributive property. Remove the common factor to outside parentheses:
3(m +n) = a multiple of 3

The rewritten equation is:
" - 3x² + 30 + 225 = 0 " ;
which is ultimately simplified to:
" x² − 10 − 75 = 0 " .

The number of days is: "15 days" .

Explanation:
______________________________________________
Given:
h(x) = - 3x</span>² <span>+ 30 + 225 ;
Rewrite as: " </span>- 3x² + 30 + 225 = 0 " ;
__________________________________________________________
Multiply EACH SIDE of the equation by "-1" ; to get rid of the "-3" ;
-1 * {- 3x² + 30 + 225 = 0} ;
to get: " 3x² − 30 <span>− 225 = 0" ;
Divide EACH SIDE of the equation by "3" ; to simplify; since:
"3", "30", and "225" are divisible by "3" ;
{</span>3x² − 30 − 225} / 3 = 0 / 3 ;
to get:
______________________________________
" x² − 10 − 75 = 0 " ;

Let us factor:
-15 + 5 = -10 ;
-15 * 5 = -75 ;
_______________________________________
Rewrite as:
(x − 15) (x + 5) = 0 ;
x = 15; and x = -5 ;

The number of days cannot be "negative value"; so we stick with:
"x = 15 days"
