Explain why graphs show the first quadrant but omit the other three quadrants.
vampirchik [111]
It's because if you are only working with positives, then the first quadrant is the only one that can help you, if you draw the other 3, then you just take up too much space to represent something you don't even need to show

POLYGONS ABCD & EFGH ARE SIMILAR. WHAT IS THE PERIMETER OF EFGH WHEN AD = 12, BC = 8, FE = 15, FG = 10, and GH = 5?
zzz [600]
It would be helpful to draw the figures, you will see that for ABCD there 2 lacking side lengths which are AB and CD. For EFGH, there is one lacking side length which is EH. We use the ratios of the corresponding sides to determine side EH. We do as follows:

FG / BC = EH / AD
10 / 8 = EH / 12 
EH = 15

Therefore, the perimeter would be:

15+10+5+15 = 45 units

The perimeters of the triangles shown are equal.Find the side length of each triangle.
Anna11 [10]
I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54

Yes the value of X is 12.53 :)

Pythagorean theorem.

11•11=121+6•6=36=157
The square root of 157=12.53
