Find the distance between the two points rounding to the nearest tenth (if necessary). (-3,0) and (3,7)

Which of these choices show a pair of equivalent expressions?

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)-144x+360 what am i doing wrong?

Can somebody 1. what is the formula for finding the vertical distance between two points on a coordinate plane?
