The coefficient of the product of (-5xy2) and (-4x2y) is

Algebra 1: unit 6 part 2 of test a) the table shows a linear function. x 0 1 2 3 5 13 21 29 37 45 53 (a) determine the difference of outputs of any two inputs that are 1 unit apart. show your work. (b) determine the difference of outputs of any two inputs that are 2 units apart. show your work.

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

Could somebody me with this radical simplification?
