Since there are three variables and three constants you add like terms.
3(x+15) = 3x + 40
To find area you need to multiply
length x width
Since 49 can be square rooted it equals seven
L x W = Area
Area = 7 x 7
Area = 49
Meaning since it’s a square the perimeter is
7 by 7 by 7 by 7 in other words 7 + 7 + 7 + 7 OR 7 x 4(equal sides)
You distribute the three into the numbers in parentheses. -3+24n+6n. Then combine like terms. -3+30n
But I may be wrong.
Answer:
12 centimeters
Step-by-step explanation:
96=6L+2W
6+2=8
96/8=12
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).
