Question
In the figure shown, 
is parallel to 
and AB = CD. What is the perimeter of quadrilateral ABCD?
The correct answer is: 56
BCFE is a rectangle & 
are congruent with base 8 & height 6.
By pythagoras theorem, AB = 10.
Perimeter of ABCD = AB + BC + CD + DA = 10 + 10 + 10 + 26 = 56.

The equation h = 150 + 10t gives the total number of housing units, h, in a community t months after a new zoning law was passed. How many housing units are added to the community each month after the zoning law was passed?
A graph illustrates the connection between two or more variables. An upward-sloping curve denotes a clear correlation between the two variables, and a curve with a downward slope denotes a negative correlation between the two variables.
A relationship between two variables can be measured and described using the statistical approach of correlation. Typically, the two variables are not changed. Therefore, two identical-person scores are necessary for the association. These results are represented as X and Y.

From 1990 to 2001, German currency included coins called pfennigs, worth 1 pfennig each, and groschen, worth 10 pfennigs each. Which equation represents the number of pfennig coins, p, and groschen coins, g, that have a combined value of 85 pfennigs?
Isolating a variable entails rearranging an algebraic equation so that one variable stands alone. A goal is to select a set of operations that will leave the variable of interest on one side of the equal sign while putting all other terms on the other.
¶To isolate a quantity in a formula or equation:
1. Make a note of the original equation. If necessary, convert the word problem or context into an equation.
2. Begin isolating the desired quantity by performing the operation on both sides of the equation.
3. Repeat Step 2 until you have isolated the desired quantity.
