Answer:

The answer is "Option C".

Step-by-step explanation:

This study looks after results including such illness growth during the trial time, and this includes additional elements such as suspected risk or source of protection (s). The study usually consists of taking and looking at such a cohort of subjects for a long time. The main advantage of these studies is knowledge accumulation and higher efficiency. Systematic reviews may suffer from choice distortion, in addition to the potential indication misinterpretation.

The Area of Shaded region is equal to the difference in Area of rectangle and Area of triangle .

let's solve for area of rectangle :

➢ \:  \: length \times width

\longrightarrow8 \times 3x

\longrightarrow24x

Now, Area of Triangle :

➢ \:  \dfrac{1}{2}  \times base \times height

\longrightarrow \dfrac{1}{2}  \times 4 \times x

\longrightarrow2x

So, the area of the shaded region in terms of x :

\longrightarrow24x  - 2x

\longrightarrow22x

And since, Area of Shaded region = 44 cm²

By equating the area, we get

\large \boxed{ \boxed{22x  = 44}}

Value of x = 2

Bill has a box of markers that has a base of 8 cm by 20 cm and a height of 6 cm. Martin's pencil box has a height of 4 cm and a
Maslowich
Ok so you need to multiply the length, width, and height together for each one.
Bill: 8 x 20 x 6 = 960
Martin: 4 x 15 x 16 = 960
So Bill is right, they both have the same volume.
