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.
D. The denominator will have three terms here when simplified. This will not be equal.
The answer is = 2xy + 2x + 2y
The 3 in the hundreds place (value of 300) has a value that is 10x the 3 in the tens (value of 30).
The answer is the square root of 18 because of Pythagorean theorem
If your 2 means "u squared" then
Just do 8-42=-34
The answer is -32u^2
I use ^ to show exponents
