$\large\boxed{D)\ x^2(3x^2+2x-9)-5x(3x^2+2x-9)}$

Step-by-step explanation:

$\text{Use the distributive property}\ a(b+c)=ab+ac.\\\\(x^2-5x)(3x^2+2x-9)=(x^2)(3x^2+2x-9)+(-5x)(3x^2+2x-9)$

z-score = 0.741

Step-by-step explanation:

The provided information are:

Population mean $(\mu)$ = 103

Population standard deviation $(\sigma)$ = 2.7

Score (X) = 105

The formula to calculate the z-score is:

$z=\frac{X-\mu}{\sigma}$

The z- score can be calculated as:

$z=\frac{X-\mu}{\sigma}\\z=\frac{105-103}{2.7} \\z= 0.741$

Hence, the z-score is 0.741.
