Brut [27]3 years ago
3 0

Answer:

Area of the Net is incorrect

Step-by-step explanation:

Base Surface Area =  π×12^2

=  452.38934211693 inches^2

Lateral Surface Area =  π×12×√12^2 + 15^2

=  724.1762903163 inches^2

Total Surface Area = 1176.5656324332 inches^2

The quotient of-54 and 9, subtracted from 8 times a number, is-18
AysviL [449]
The number is:  " -3 " .
_____________________________________
Explanation:
_____________________________________
Let "x" be the "unknown number" for which we are to solve.

        8x − (-54/9) = -18 ;  Solve for "x" ; 

  →  8x  − (-6) = - 18 ;

  →  8x + 6 = - 18 ;

   Subtract "6" from each side of the equation:

  →  8x + 6 − 6  =  - 18 <span>− 6 ;

to get:   8x =  -24 ;

Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the equation ; & to solve for "x" ; 

              8x / 8 = -24 / 8 ;

to get:   x = -3 .

The number is:  " -3 " .
