<u>Given</u>:
It is given that the height of the rectangle is 
The width of the rectangle is 
We need to determine the area of the entire rectangle.
<u>Area of the rectangle:</u>
The area of the rectangle can be determined using the formula,

Substituting the values, we have;

Multiplying each term within the parenthesis, we get;

Simplifying, we get;

Adding the like terms, we have;

Thus, the area of the entire rectangle is

f(8)=2.8+5=21
g(8)=3.8+6=30
f-g(8)=21-30= -9
Answer:
.43
Step-by-step explanation: you would right and move the decimal twice to get .43 hundreths
To identify the dependent variable in the testable, look out for the variable that is affected by the other. The variable that changes as a result of another variable is the dependent variable.
In a research study, there are typically two main variables that direct the scientific enquiry. They are:
- Dependent Variable, and
- Independent Variable
The independent variable causes a change in the dependent variable, i.e. the dependent variable receives the <em>effect</em>, the independent variable is the <em>cause </em>of the change.
It is very easy to identify the dependent variable in any testable hypothesis once you are able to pick out which variable is causing a change in the other.
For example, let's say the topic of a research is: <em>The Impact of Sunlight on Germination Rate of Seedlings.</em>
Here, <em>Sunlight </em>is the independent variable affecting <em>Germination Rate</em>.
The dependent variable here would be: <u><em>Germination Rate.</em></u>
Therefore, to identify the dependent variable in the testable, look out for the variable that is affected by the other. The variable that changes as a result of another variable is the dependent variable.
