Answer:
B) First, find two areas using (4m x 10m = 40m2) and (8m x 3m = 24m2). Next, add (40m2 + 24m2 = 64m2).
Step-by-step explanation:
Samuel should is looking to find the area of his basement in order to cover it with carpet.
An area is calculated by multiplying two dimensions (so answers A and D are not it).
Best solution is to divide the area into two large rectangles then ADD them together to get the total area.
The only scenario where he could have subtracted something based on his plan is if he would have multiplied the 10m by the 12m then subtracted the area that is not part of his basement (7mx8m). He would have achieved the same result of course, but by going a different way.
Answer: $26.4 Australian dollars
Y=1.2x
Plot all points on the coordinate plane and combine these points by lines to get triangle ABC (see attached picture for details).
Write the equation of side AB:
To find y-intercept you have to substitute x=0, then:
The point 
is the point where line AB intersects y-axis.
Of these choices, the best is the last:
run 1/rise 1 = run 2/rise 2
_____
While this will show the slope is the same everywhere, it does so by actually showing the inverse of the slope is the same everywhere. Slope is defined as
slope = rise/run
