Answer:
1) 2x^3-2x^2+4x+20
Step-by-step explanation:
line up the equations, having each variable aligned with the similar variable, and distribute the minus sign across the parenthesis
7x^3 + 4x + 13
-(5x^3 + 2x^2 - 7)
---------------------------------
2x^3 - 2x^2 +4x +20
Answer:
3600 degree
Step-by-step explanation:
the sum of the interior angles of a polygon of n sides is
sum =180∘(n−2)here
=22⇒sum of interior angles =180∘×20 3600
Answer:
1798 and 32798
Step-by-step explanation:
31000/100=310
310x5.8=1798
