Answer:
A and C
Step-by-step explanation:
Equivalent expressions are expression which when simplified to lowest terms are equal.
Simplify each answer choice to find the expression which simplifies to
.
A. Multiply the exponents 3*2 = 6. This is equal.
B. Multiply numerators and denominators. Here the numerator will be 1*1 = 1. It does not equal 2 in the numerator.
C. Here the numerator does equal 2. The denominator multiplies to 
This is equal.

Answer:
x = 12
Step-by-step explanation:
we can put this is a proportion: (new side 1) / (old side 1) = (new side 2) / (old side 2)
so in this case, 18 would be old side 1, x would be new side 1
12 would be old side 2, and 8 would be new side 2
plug these in: x/18 = 8/12
cross multiply 18 and 8: x = 144/12
now simplify: x = 12
