Answer:
m + s = 30
2m + 6s = 100
Step-by-step explanation:
took the test
First, let's find g(4). After we find it, we can substitute the value into 
.
To find g(4), we need to substitute x = 4 into the function 
, as shown below:
Now that we have found g(4) = 9, we can substitute this value in for 
in .
f(g(4)) is equal to 28.
Answer:
C. (3x)^2 - (2)^2
Step-by-step explanation:
Each of the two terms is a perfect square, so the factorization is that of the difference of squares. Rewriting the expression to ...
(3x)^2 - (2)^2
highlights the squares being differenced.
__
We know the factoring of the difference of squares is ...
a^2 -b^2 = (a -b)(a +b)
so the above-suggested rewrite is useful for identifying 'a' and 'b'.
