You just need to use your test-taking skill to eliminate the wrong answers here.
There is no such thing as a "Congruent Angles Postulate," so the last two choices can be eliminated.
The AA Similarity Postulate refers to triangles, not angles, so the second choice can be eliminated.
That only leaves the (correct) first choice.
Side a can be broken into to rectangles having areas:
(12-8)*4 and 8*12 so the area of side A is
A=16+96
A=112cm^2
You can see solution in the picture, hope that can help you :-)
Take it as 19 and 0.07, then the mixed no. Is 19 7/100 since 0.07 is 7/100
Answer:
All x-coordinates are different, so this relation is a function.
Having the same y value more than once is not a problem for a function.
"This (does not/does) represents a function because different (x values/y values) can have the same (x values/y values)."
