Answer:
5x and 2x
Step-by-step explanation:
In addition, add the terms with the same variable and the same variable exponent
5x + 2x = 7x correct
2x² + 3x = 2x²+3x you cannot combine these terms because they have different variable exponent
In multiplication, multiply the two terms with the same variable and add their exponent
5x • 2x = 10x²
5x • 2x = 10x¹+¹
=10x²
