If the public debt of the united states of apex is 9,529,034,179,824,022 apex dollars and its gross domestic product (gdp) is 16,247,683,987,248,007 apex dollars, then its debt-to-gdp ratio is about 171%. true or false?

To compute for the debt-to-GDP ratio, we just have to divide the debt given in this item by the GDP and convert the quotient to percentage. That is,
                debt-to-GDP ratio = (9,529,034,179,824,022)/                              (16,247,683,987,248,007) x 100%
                debt-to-GDP ratio = 58.65%
Thus, the answer is FALSE. 

Hey!

The x-term has a coefficient of 2: 2x

The z-term has a coefficient of -1: -z

Together: 2x - z

The expression has a constant less than zero = 5 + 2z² (When it says a constant term less than zero you can assume that it can be any number being subtract by z).

Final 2x - z - 5 + 2z²

Hope This Helped! Good Luck!
