14.87
Step-by-step explanation:
use the Pythagorean theorem
a^2+b^2=c^2
C being the longest side of the triangle
14^2+5^2=C^2
196+25=C^2
221=C^
find the square root of 221
C=14.866
rounded to nearest tenth
C=14.87

The 8 sides of the regular octagon are all the same length, so the perimeter of it is 8*(12.4 in) = 99.2 in.
The area of a regular polygon is half the product of the perimeter and the apothem.
area = (1/2)(99.2 in)(15 in) = 744 in²
The area of the stop sign is 744 in².
4x+3y “more than” 20
5x+y “less than” 16
This are the two system of inequalities.
