x = 0.17(repeating 7) (1st)
10x = 1.77 (2nd)
subtract (1st) from (2n)
9x = 1.77 - 0.17
9x = 1.6
90x = 16
x = 16/90
x = 8/45
answer
8/45
Answer:
927 cubic inches
Step-by-step explanation:
The area of the octagonal base is ...
A = (1/2)Pa
where P is the perimeter, and 'a' is the apothem. Using the given numbers, the base area is ...
A = (1/2)(8·4)(4.83) = 77.28 . . . square inches
The volume of the prism is given by ...
V = Bh
where B represents the area of the base, and h is the height.
V = (77.28 in^2)(12 in) = 927.36 in^3
The volume of the prism is about 927 cubic inches.
X=.5 digressed bsquare +.2= 11.23987
There would be no solutions. 13x cancels each other out in the equation, so you would have no X all together.
