The interval of the function y = x² + 12x + 27 positive will be (-∞, -9) and (-3, ∞). Then the correct option is D.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The function is given below.
y = x² + 12x + 27
The roots of the function are given as,
y = 0
x² + 12x + 27 = 0
x² + 9x + 3x + 27 = 0
x(x + 9) + 3(x + 9) = 0
(x + 3)(x + 9) = 0
x = -3, -9
The interval of the function y = x² + 12x + 27 positive will be (-∞, -9) and (-3, ∞). Then the correct option is D.

What is 900 divided by 3, and why?
Answer:
300
Explanation:
look at the file below
300 is the quotient or the result of dividing 900 by 3.
The result of dividing 900 by 3 is 300.
To understand why, we perform the division operation:
= 900 ÷ 3
= 900 /3
= (3 x 3 x 2 x 2 x 5 x 5) / 3
= 3 x 2 x 2 x 5 x 5
= 3 x 4 x 25
= 12 x 25
= 300
When we divide 900 by 3, we are essentially splitting 900 into three equal parts. Each part is 300.
Therefore, 300 is the quotient or the result of dividing 900 by 3.

Answer:
D. 137 [tex]m^{2}[/tex]
Step-by-step explanation:
First, get the area of the rectangle:
[tex]A_{Rectangle} =length *width[/tex]
[tex]A_{Rectangle}=(15)(11)=165[/tex]
Then, get the area of the triangle:
[tex]A_{Triangle} =\frac{height*base}{2}[/tex]
[tex]A_{Triangle}=\frac{8*7}{2} =28[/tex]
Now substract the area of the triangle from the rectangle:
165 - 28 = 137
∴ 137 [tex]m^{2}[/tex]
