The answers are
x=5
n=3
y=4
k=-80
Answer:
Your first instinct might be to go ahead and add the x terms together, BUT this would be a bad thing to do! You cannot combine the x2 and 2x, because the first term has an exponent (2) and the second one does not have an exponent; therefore, you cannot add them together!
Step-by-step explanation:
You would need one because you arent yet to 20 so it takes one tenth for example;
1.7 or 7/10
Thats my guess tho man if it is more complicated than that, SORRRYYYY
