Answer:
- 48
Step-by-step explanation:
If you want to learn more about this concept, it's called composition of functions.
First, you plug in g(x) as if it were x into f(x).
f(g(x))= -5 (1/2x + 4) + 2
= -5/2x - 20 + 2
= -5/2x - 18
Then, plug in the value given, as x.
= -5/2 (12) - 18
= -30 - 18
= - 48
I hope this helped!

Answer:
1.33 liters
Step-by-step explanation:
Volume of any shape is given by cross sectional area multiplied by height. Therefore, V=Ah
Where A is area and h is height
Since their cross sections are the same, then volume depends on height.
If 12cm equals 2 liters
8cm equals x
X=(2*8)/12=1.3333333333333 liters
Approximayely, the smaller pail has capacity of 1.33 liters
Since the equation, <span>h=1.6a+41, is linear, we know that the coefficient of x, or in this case a, is the slope. Therefore the correct answer would be

Answer:
triangle: 5x-8
square: 4x+8
Step-by-step explanation:
triangle: 2x + 2x + x -8
combine like terms
= 5x-8
square: x + 2 + x + 2 + x + 2 + x +2
combine like terms
= 4x + 8
