A picture types of the models would be helpful.. but they could be found in a rectangular shape or square such as width=2 and length =12 vise versa or w=4 and length = 6 , etc etc
64 inch = 162.56 centimetres
You start with what is in the parenthesis which is subtraction and then do addition after that add again
Arrange data set in ascending order
1, 5, 5, 5, 5, 6, 6, 7, 30
mean = 7.78
mode = 5
median = 5
The least appropriate measure for describing the data set is MEAN. This is because it is affected by the outlier, 30.

So to solve for the value of a variable in an equation, you would need to isolate x on one side. The first thing you have to do is multiply 2 and (x + 7) together, which can be rewritten as 2(x) + 2(7). After multiplying, your equation would be:
, or A.

So the rule with multiplying exponents with the same base is to add the exponents together, and the rule with dividing exponents with the same base is to subtract the exponents. Your equation will be simplified as such:

Now the rule with converting negative exponents into fractions is
. In this case, 4^-2 would turn into
, or C, which is your final answer.
