Answer: whichever one is easiest to get by itself.
Step-by-step explanation:
Answer:
a) w = 8; y = 5.25
b) x = 10; z = 7.2
Step-by-step explanation:
a) Dimensions on the smaller figure are FA/F'A' = 3/4 times those on the larger figure.
6 = (3/4)w
w = 24/3 = 8
y = (3/4)·7 = 21/4 = 5.25

b) Dimensions on the smaller figure are ER/E'R' = 9/15 = 3/5 times those on the larger figure.
6 = (3/5)x
x = 30/3 = 10
z = (3/5)12 = 36/5 = 7.2
Reduce the expression by cancelling the common factors: 1/n
As, synthetic division by -4 gives remainder 0. Hence, Option B is correct. -4 is a root of 
As, x+4=0 gives x=-4.
So, option C is correct,
(x+4) is factor of
Option E is correct
