All i know is that it isnt 5.4

I found the answer its 4.5 how i got this is how

So this shape is a prismoid

To find the length of the side in the middle you have to add

So, IJ= DA + FG and divide the whole thing by 2
IJ=6+3/2
=4.5

Answer:

Option D. 4.5

Step-by-step explanation:

In the given diagram FGAD is the trapezoid with the given sides FG = 3 units and AD = 6 units.

Now we have to calculate the Median IJ.

Since median of a trapezoid is represented by the formula = $\frac{1}{2}(FG + AD)$

Therefore, median IJ = $\frac{1}{2}(3+6)$

= $\frac{9}{2}$

= 4.5

Therefore, Option D. 4.5 will be the answer.

Answer:

The given fraction $\frac{x^3-x^2}{x^3}$ reduces to $\frac{x-1}{x}$

Step-by-step explanation:

Consider the given fraction $\frac{x^3-x^2}{x^3}$

We have to reduce the fraction to the lowest terms.

Consider numerator $x^3-x^2$

We can take x² common from both the term,

Thus, numerator can be written as $x^2(x-1)$

Given expression can be rewritten as ,

$\frac{x^3-x^2}{x^3}=\frac{x^2(x-1)}{x^3}$

We can now cancel $x^2$ from both numerator and denominator,

$\Rightarrow \frac{x^2(x-1)}{x^3}=\frac{x^2(x-1)}{x^2 \cdot x}$

$\Rightarrow \frac{(x-1)}{x^2 \cdot x}=\frac{x-1}{x}$

Thus, the given fraction $\frac{x^3-x^2}{x^3}$ reduces to $\frac{x-1}{x}$
