(2x)(10x)
A) 20x
B) 12x
C) 20x^2
D) 5x
C) 20x^2
To simplify the expression (2x)(10x), you can use the distributive property of multiplication.
Step 1: Multiply the coefficients (numbers in front of the variables): 2 * 10 = 20.
Step 2: Multiply the variables: x * x = x^2.
Therefore, the simplified expression is 20x^2.
C) 20x^2 is the correct answer.
