Area of polygon
=n(base * apothem)/2
=5*9*8/2
=180 mm^2
Volume of prism
=cross-sectional area * height
=180*28
=5050 mm^3
Answer:12
Step-by-step explanation: 3 x (2x2)= 3x4= 12
6.71 miles
use the Pythagorean theorem
6^2 + x^2 = 9^2
36 + x^2 = 81
81-36= 45
square root of 45 is approximately 6.71 miles
4x-35=9x
-4x
-35=5x
divide by 5
x= -7
Let point A be
and point B 

Use the point-slope formula and whichever point you want as
, in this case I'll use
