Answer:
-2 < x<4
Step-by-step explanation:
We have open circles and -2 and 4 so we don't include those numbers
The line is in between so the x is in between
If QR is a median, then:
We have NO = 30, MP = 9x - 42 and QR = x + 15. Substitute:
The order is (-10,-1,0,1,10)
Its 500
because anything that is getting multiplied by one is the same number.
