Answer:
540 degrees
Step-by-step explanation:
Triangles ( 3 sides )
180 degrees
Squares ( 4 sides )
360 degrees
Pentagon ( 5 sides)
540 degrees
Hexagon ( 6 sides )
720 degrees
Any Polygon can be calculated using this formula:
n = number of sides
(n - 2) * 180 degrees
*Note, this is only for the sum of the interior angles. Exterior angles on polygons are ALWAYS equal to 360 degrees.
I think it's the last point. (5,4)
(2x-3)(x+5)
Use foil to simplify, First multiply together the first terms of the pairs, then the outer terms, the middle terms, and finally the last terms. Then combine like terms.
2x^2+10x-3x-15 equals 2x^2+7x-15
