<h3>Answer:</h3>

56 ft by 40 ft

<h3>Explanation:</h3>

If we let x represent the multiplier for the ratio, then the perimeter is ...

... 2 × (7x +5x) = 24x = 192 ft.

Dividing by 24 gives

... x = 8 ft.

The dimensions are 7 and 5 times this multiplier, or ...

... 7×8 ft = 56 ft . . . . by . . . . 5×8 ft = 40 ft

If f(x)=3x-1 and g(x)=x+5, find (f o g)(x) and (g o f)(x)<br><br> (f o g)(x)=<br><br> (g o f)(x)

Nuetrik [128]

Answer:

(f o g)(x)= 3x + 14

(g o f)(x) = 3x + 4

Step-by-step explanation:

(f o g)(x) = f(g(x)) = f(x + 5) = 3(x + 5) - 1 = 3x + 15 - 1 = 3x + 14

(g o f)(x) = g(f(x)) = g(3x - 1) = 3x - 1 + 5 = 3x + 4
