Answer:
49x + 114
Step-by-step explanation:
[ [ fireplace ] x = area of 5
] x + 6
5x
patio = area of 5
+ 49x + 114
5x + 19
(5x + 19) ( x + 6) = 5
+ 19x + 30x + 114
(5
+ 49x + 114) - (5
) = 49x + 114
(area of patio and fireplace) - (area of fireplace) = (area of patio only)

Answer:
<em>The domain of f is (-∞,4)</em>
Step-by-step explanation:
<u>Domain of a Function</u>
The domain of a function f is the set of all the values that the input variable can take so the function exists.
We are given the function

It's a rational function which denominator cannot be 0. In the denominator, there is a square root whose radicand cannot be negative, that is, 4-x must be positive or zero, but the previous restriction takes out 0 from the domain, thus:
4 - x > 0
Subtracting 4:
- x > -4
Multiplying by -1 and swapping the inequality sign:
x < 4
Thus the domain of f is (-∞,4)
