Answer:
g(f(x)) = -x - 18
Step-by-step explanation:
2x - 6( (x + 6) / (2) )
2x - 3( x + 6)
2x - 3x - 18
-x - 18
Answer:20
Step-by-step explanation:
2(3-4)-(8+3)
2(1)-(11)
2-22
slope intercept form is y=mx+b
so solve for y
2x+y=-3
minus 2x both sides
y=-2x-3
-2y=6+4x
divide both sides by -2
y=-3-2x
y=-2x-3
Answer:
5 and 7
Step-by-step explanation:
5 and 7 are the nearest integers, and 6 is right in between them
We can see that window is in shape of rectangle. So the length of the required wood to frame window is equal to the perimeter of rectangle.
SO the length of rectangular window is

feet.
Width of the rectangular window is =

feet.
In general parameter of rectangle is =

So the parameter of window is =

So the required length of wood to frame window is = 28.834 feet
