Answer:
x= 28
Step-by-step explanation:
10/70=4/x
The room is 18 ft by 26 ft which is 468 ft^2
She can afford a 240 ft^2 rug
12 * 20 = 240
She can afford a rug that is 12 ft wide by 20 ft long
Step-by-step explanation:
m > n <em>add 2.1 to both sides</em>
m + 2.1 > n + 2.1 TRUE
m > n <em>subtract (-4) from both sides</em>
m - (-4) > n - (-4) TRUE
m > n <em>add 16.5 to both sides</em>
16.5 + m > 16.5 + n TRUE
m > n → 3 + m > n <em>logic</em>
3 + m > n <em>add 6 to both sides</em>
9 + m > 6 + n TRUE
Answer:

Step-by-step explanation:
Because we have to rewrite this equation in the format
, we have to divide, or factor to find basic terms,
Expanding the value of k(x), we have
. We see that each term can be divisible by 4, so we can factor out 4 to get

Now, we have two different terms getting multiplied. We can separate the two to get 
Because we are multiplying 4 by the other term, this is represented by 
Now, we can just set f(x) and g(x) to these functions:

Now, just to make sure, we can plug a value into k(x) and the same value into f(g(x)). Plugging in 1, we have (2(1)+4)2 as 2(2+4), which is 2(6) = 12.
Plugging 1 into f(g(x)), we can evaluate g(1) first, to get 1 + 2 = 3. Now, f(3) = 4(3)= 12, which is the same for k(x).
