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 )
x = 9
When multiplying two powers that have the same base, you can add the exponents.
The square root of 12 is 3.4641 so 3.6 would be greater than 3.4641
