F(-4) = 0
Here, we replace x with -4. In doing so, we see that (-4+4) is indeed 0, making this the correct answer.
The next two choices are incorrect since only -4 is a root of f(x), as explained above (a root occurs when the function equals zero when plugging in that “root”).
The last answer is incorrect since plugging in 4 will get f(4)=8.
Answer: 21 hours
Step-by-step explanation:
The lawn order can produce 10 landmowers in 7 hours.
This means that their speed is:
= 10/7
= 10/7 landmowers per hour
If they want to produce 30 lawnmowers, the amount of time they will take is:
= 30 ÷ 10/7 per hour
= 21 hours
90=0 so therefore the answer is right there 100%
There are probably mutliple solutions to this but heres one I found
x=0
