It's in simplist form
Since the drawing is in inches, the scale will be 1/4
You already said the answer
Since every inch is three feet, you multiply three by each of ther measurements and find the area.
First, you must use the distributive property.
12x + 36 = 8x + 36 + 4x
then combine like terms
12x + 36 = 12x + 36
Since that is correct, your answer will either be same line/equal/yes or something like that.
Divide the top and bottom by eight
3/4
It would be 1/3
1/3 is biggest, because it keeps going.
We need to expand to see why
0.3 = 0.300000000000000
0.33 = 0.330000000000000
1/3 = 0.33333333333333333
okay, here we go
You need to use a special version of the pythagorean theorum
15^2 _ 10^2 + 12^2
225 _ 100 + 144
225 _ 244
since 225 is less than 244, it is an obtuse triangle
