Set up a ratio as a fraction:
_______________________________________________________
8/3 = 320/x ;
_______________________________________________________
Cross-multiply:
_____________________________________________________
8x = 3 * 320 ;
8x = 960 ;
Divide each side of the equation by "8" ;
to isolate "x" on one side of the equation ; and to solve for "x" ;
______________________________________________________
8x / 8 = 960 / 8 ;
to get: x = 120 .
The answer is: [A]: " 120 ft² " .

Step-by-step explanation:
The answare is c because the voulme would be 150 because 30*5 =150
Step-by-step explanation:
If f(x)=3x+2and g(x)=x^2-9
find (f-g)(x)
f(x)- g(x) = [3x + 2] - [x^2 - 9]
= -x^2 + 3x + 11
