nine add 7 to get from -7 to 0 then add 2 to get to 2 7 + 2 = 9
You add 7 -5 + 7 = 2
you need to add +9 +9-7 = +2
-7
They are 7 and 2
Both numbers add up to 7
9
add them all together then divide by 7
-7 and +1
They can be: -2+(-5) = -7
-19
The interior angles of a polygon with n sides add up to (n-2)*180 degrees.Here, n = 7 so the answer is (7-2)*180 = 900 degrees.The interior angles of a polygon with n sides add up to (n-2)*180 degrees.Here, n = 7 so the answer is (7-2)*180 = 900 degrees.The interior angles of a polygon with n sides add up to (n-2)*180 degrees.Here, n = 7 so the answer is (7-2)*180 = 900 degrees.The interior angles of a polygon with n sides add up to (n-2)*180 degrees.Here, n = 7 so the answer is (7-2)*180 = 900 degrees.
