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"

Answer:
1/3
Step-by-step explanation:
9/27 simplified is 1/3
4x=11 is the correct answer:)
The answer is False.
Similar figures are shapes where one looks like a miniature, larger, flipped, and/or rotated version of the other. Thus, they will have sides that are proportional to each other and will have same angle measurements.
MNOP is a parallelogram, while QRST is a square. They are not similar because they do not have congruent angle measurements although the corresponding sides are proportional.
(Interesting property regarding similarity: Any square is similar to another square)
