A=4
B=0
C=7
X=16
This is what I think
Answer:
the answer can be found in cases like this , the answer is 20
D=45h
For example: 45mph times 2 hours equals 90 miles traveled
There are two ways to do this.
The first way is to algebraically find (f+g)(x) first and plug in x = 5 later. Doing that method leads us to
(f+g)(x) = f(x) + g(x)
(f+g)(x) = 6x+3 + x-4
(f+g)(x) = 7x-1
(f+g)(5) = 7(5)-1
(f+g)(5) = 34
OR
you can compute f(5) and g(5) first, then add up those sub-results to get
f(x) = 6x+3
f(5) = 6(5)+3
f(5) = 33
g(x) = x-4
g(5) = 5-4
g(5) = 1
Adding up these results gives: (f+g)(5) = f(5) + g(5) = 33+1 = 34
Either way, the final answer is 34
Answer:
126 = n × (n - 5)
Step-by-step explanation:
If Nikki's age is <em>n </em>and she is 5 years older than Jamie, then Jamie is 5 years younger than Nikki's <em>n </em>number of years.
