Finger [1]

Answer:

49x + 114

Step-by-step explanation:

[   [ fireplace ] x   = area of 5x^{2}                   ]  x + 6

     5x

   patio               = area of 5x^{2} + 49x + 114

5x + 19

 

(5x + 19) ( x + 6) = 5x^{2} + 19x + 30x + 114

(5x^{2} + 49x + 114)                     -   (5x^{2} )                         =           49x + 114

(area of patio and fireplace) - (area of fireplace)     =       (area of patio only)

2. What is g(6)and what does it represent in the context of this example?
ahrayia [7]

Answer:

g(x) = 30

Step-by-step explanation:

Let the function representing line in graph 2 is,

g(x) = mx + b

Here m = slope of the line

b = y-intercept

Since the given line passes through origin (0, 0), y-intercept of the function will be 0.

Slope of the line = \frac{\triangle y}{\triangle x}

                           = \frac{10}{2}

                           = 5

Therefore, function will be g(x) = 5x

For x = 6,

g(6) = 30

This function represents that height of liquid in the cylinder is directly proportional to the amount of liquid poured in the cylinder.
