These two regular pentagons are similar. the length of each side on pentagon a is 4 cm. the length of each side on pentagon b is 6 cm. what is the scale factor from pentagon b to pentagon a? ' a) 0.5 b) 1.5 c) 2.0 d) 2.5

We know that
pentagon A is the smaller pentagon> length side 4 cm
and  
pentagon B is the larger pentagon> length side 6 cm
so
the scale factor from pentagon B to pentagon A=length side B/length side A
6/4> 3/2---> 1.5

the answer is the option 
B)1.5 

Y= -2x-1 the negative in front of the 2 is because the slope is negative and the -1 is because it’s down 1 on the y axis.
