Answer:
is this a collage question?
Step-by-step explanation:
6 (7 n - 5 m) + 8 m
6 (7 n - 5 m) = 42 n - 30 m:
42 n - 30 m + 8 m
Grouping like terms, -30 m + 42 n + 8 m = 42 n + (8 m - 30 m):
42 n + (8 m - 30 m)
8 m - 30 m = -22 m:
42 n + -22 m
Factor 2 out of 42 n - 22 m:
Answer: 2 (21 n - 11 m)
Answer:
To find the sum of interior angles in a polygon divide the polygon into triangles. The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. A polygon is a closed geometric figure whose sides are simple line segments. Each corner of a polygon where two sides intersect is called a vertex of the polygon. For example, a triangle is a polygon with 3 sides. There are also three vertices, one at each point.
