Answer:
x = 9
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= ( cross- multiply )
12(x - 1) = 96 ( divide both sides by 12 )
x - 1 - 8 ( add 1 to both sides )
7
If all of the sides are congruent to one another, then their corresponding values are also equal.
it is -30
you would divide both sides by x,then f=2
using PEMDAS we come to -30
-6x^2+x+8
Add -1 and 9 because they are the only like terms
