Answer:

106

Step-by-step explanation:

Ok this question is a bit confusing but once you understand the concept you will be able to answer the question correctly

Always know that bracket is solved first once it is found in the question

(+12)2+82

24+82

106

Therefore the final answer is 106

I believe you understand how we get the answer...just be careful when solving this kind of question... simple

When Determining the Relationship between my height and my weight.

BMI=WEIGHT/HEIGHT*HEIGHT.

BMI is the dependent variable

Weight and height are independent variables.

Step-by-step explanation: Mathematical representation of data or information is a very important strategy applied to solve certain Complex problems.

Mathematical representation helps to make Complex data or information easily understood,it helps one to derive the possible root cause and outcomes of problems,it also shows Relationship between various treatments or variables or drugs applied in solving problems example in treatment of Diseases.

BMI(BODY MASS INDEX) is a life situation where I have used Mathematical representation to solve, it used to show how your height and weight is related.

Independent variables are variables that do not cause any changes t other variables when altered.

Dependent variables are variables which can cause change in a situation when altered.

In this case BMI depends on The weight and height of a person, while the Weight and height of a person are independent on the BMI.
