Answer:

Option (1) is correct.

The product of $(y+3)(y^2-3y+9)$ is $y^3+27$

Step-by-step explanation:

Given, $(y+3)(y^2-3y+9)$

We have to find the product of above,

We have to multiply each term as ,

$(y+3)(y^2-3y+9)$ can be written as,

$\Rightarrow y(y^2-3y+9)+3(y^2-3y+9)$

When we multiply each term we get,

$\Rightarrow (y^3-3y^2+9y)+(3y^2-9y+27)$

These terms are same as we have filled in table below.

On adding like terms we get,

$\Rightarrow y^3-3y^2+9y+3y^2-9y+27$

$\Rightarrow y^3+27$

Thus, the product of $(y-3)(y^2-3y+9)$ is $y^3+27$

The gestation period of humans (266 days) is___ percent longer than the gestation period of pigs(115 days).

bija089 [108]

If we take 115 to be the 100%, how much is 266 off of it then?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
115&100\\
266&p
\end{array}\implies \cfrac{115}{266}=\cfrac{100}{p}\implies p=\cfrac{266\cdot 100}{115}
\\\\\\
p\approx 231.3$

so 266 is about 231% of 115, which is 131% more than 115.
