X²-13x-30=0
(x-15)(x+2)=0
x = -2 or 15
Answer:
slope it's a slope and I need 20 characters
a) Corresponding angles of similar figures are congruent, so 
b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is 
c) Since the scale factor is 5/2,

Fixed pay+variable pay=total pay
100+pay per km times number of km=total pay
100+0.2k=p
p=0.20k+100
