Answer:
first option
Step-by-step explanation:
solving the inequality
- 13 > - 5x + 2 > - 28 ( subtract 2 from each interval )
- 15 > - 5x > - 30
divide each interval by - 5 , reversing the symbols as a result of dividing by a negative quantity.
3 < x < 6
since the symbol is < then end values will be an open circle with the values between shaded blue, that is the first graph
1. 6, 12, 18
2. 8,16,24
3. 12, 24, 36
4. 15, 30, 45, 60
4. 30, 60, 90
Hello!
I was looking for this answer as well, but I took the quiz and got it correct. The answer is 5 units.
good luck!
Your question is a difference of squares. both terms that need to be factored are squared. to solve take the square root of each put into two terms one of addition and one of subtraction.
anwser= (5x-9)(5x+9)
the reason this works is because when you foil you get
25x²-45x+45x-81
the middle terms cancel revealing
25x²-81
