Well that's easy. Just plug in the numbers: 3*(-2)+4*(5)=14. So yes the solution is correct.
For this case we have the following expression:
We take common factor 
, for this we must take into account that:
So, factoring the expression we have:
ANswer:
The factored expression is:
Answer: b = 4f
Step-by-step explanation:
Since every flashlight needs 4 batteries, every flashlight added (f) will be 4 more batteries needed total (b). With this information in mind, we can write the equation:
b = 4f
Answer:
