I find it easier to do the actual computation than to try to choose the correct answer from a bunch of alternatives.
You are given the area of a rectangle, as well as the length of one side. To find the length of the other side, you must divide the given side length into the area.
Thus, the unknown side length is
1.403E(-2) cm^2
----------------------- = 0.23E2 cm, or, better, 2.3E1, or 23 cm
6.1E(-4) cm
Now that you have this info, which of the given four steps do you judge to be appropriate and which inappropriate?
Answer: The conclusion drawn from the study is *invalid* because the sample is *biased*. In this instance, an *inappropriate* study was concluded.
It’ll be -5x - 24
you multiply the 5 by 4 and it’ll be 24, and put the x with the 5 and that’ll be your answer :)
The answer is 9.
To calculate this, we will use Galileo's square cube law, used to describe the change of the area or the volume of the shape, when their dimensions increase or decrease. The formula used for change of the area is

A₂ - the area after the change,
A₁ - the area before the change,
l₂ - the dimension after the change,
l₁ - the dimension before the change.
It is given:
l₁ = 1 cm
l₂ = 3 cm
Let's use this formula for the mentioned triangle:

Therefore, the area of the triangle was multiplied by 9.
Answer:
209.22cm²
Step-by-step explanation:
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·4·(4+122+42)≈209.21889cm²
