9 = T+4
Take 4 from both sides
9(-4) = T(-4)
5=T

The sum of the exterior angles of all polygons equals to 360⁰.Since only the sum of the interior angles of all quadrilaterals equals to 360⁰, the polygon must have 4 sides.
If you take 2, and add 2 to it, it equals four.........
the two numbers are 14 and - 4.
Add 4 to both sides to cancel out the -4. Then m will equal 22
8
The factor pairs of 84 are (84,1)(42,2)(28,3)(21,4)(14,6)(12,7) None of them add up to 17. If that was -84, you could use 21 and -4.
sum means to add so..... 8 + 4 = 12
A 4 sided quadrilateral has interior angles that add up to 360 degrees and its exterior angles add up to 360 degrees
There is no set of four consecutive numbers (odd or even) whose sum equals 169.
7 + 4 = 11
If it's a quadrilaterl shape then the 4 interior angles will add up to 360 degrees in compliance with the formula: (number of sides-2)*180 = sum of interior angles
