Answer:
2 is the number because half of 5 is 2.5
If (x+5) is a factor the equation will equal zero when x=-5 so
3(-5^2)+14(-5)+k=0
75-70+k=0
5+k=0
k=-5
The answer is e none of the above
Answer:
the answer is the 2nd one :)
Step-by-step explanation:
Answer:
26
Step-by-step explanation:
Problem: f(x) = 28 + x + 7
Plug in f(-9)
New equation: f(-9) = 28 + (-9) + 7
Simplify: f(-9) = 26
<u>Answer: f(-9) = 26</u>
