Remmber
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
conver to improper
4 and 1/5=20/5+1/5=21/5
2 and 1/3=6/3+1/3=7/3
(21/5)/(7/3)=(21/5)(3/7)=63/35=9/5=1 and 4/5
Answer:
firstly We see that the ratios of corresponding sides are equal. Therefore, the sides are proportional, and the two polygons are similar.
...
If all of them are equal, then the polygons are similar:
Side 1: 4/8 = 1/2.
Side 2: 1/2.
Side 3: 5/10 = 1/2.
Side 4: 6/12 = 1/2.

Answer:
C.)-5
Step-by-step explanation:
y2-y1/x2-x1
(-9,6) (-6,-9)
-9-6=-15
-6-(-9)=3
-15/3=-5
19x + rx = -37x + w
Add 37x on both sides
19x + rx + 37x = w
Factor out the x
x(19 + r + 37) = w
You can simplify this to:
x(56 + r) = w
Divide (56 + r) on both sides to get x by itself
x = 
One number is 4 and the second number is 5.
