Answer:
A
Step-by-step explanation:
x^2 + 7x+ 10. factors out to (x - 2)(x + 5)
Answer: It is B sorry if took to long
Step-by-step explanation:
First we see that we can factor out a 5 from everybody
5(-a^2+2ab^2-4+5ba^3)
trial and eror and experience
order in poawer order
5(5a^3b-a^2+2ab^2-4)
5(a^2(5ab-1)+2(ab^2-2))
dunno how to go on further
To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.
<h3>What is the average?</h3>
Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:
- 69 seconds.
- 58 seconds.
- 45 seconds.
- 120 seconds.
- 76 seconds.
The average time of my group of friends would be:
69 + 58 + 45 + 120 + 76 = 368
358 ÷ 73.6 seconds
The average of my group of friends would be 73.6 seconds.
According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.
Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.
