What is the area of a regular heptagon with side length of 6 meters and a distance from the to the vertex of 6 meters? round your answer to the nearest tenth

Apothem = side length / 2*tan(180 / number of sides)
apothem = side length / 2*tan (180 / 7)
apothem = 6 / (2*tan( 25.7142857143))
apothem = 6 / 2*0.48157
apothem = 6.2296239384

Polygon area = (# of sides * side length * apothem) / 2
Polygon area = ( 7 * 6 * 6.2296239384) / 2
Polygon area = 130.8221027064  

A. -10 is the value of x

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
