3x = 2x + 7

x = 7

The sum of the measures of the interior angles of a convex polygon is 3960°.
scZoUnD [109]

Step-by-step explanation:

The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.

My name is Ann [436]

Answer:

Step-by-step explanation:

Let the number of floors  = x

Number of apartments per floor = 4x

4x *x = 100

4x² = 100

x² = 100/4

x² = 25

x =√25

x = 5

Number of apartments on each floor = 4*5 = 20
