Factor the problem first. So for number one, take out a seven to make it 7(x+4) and factor by subtraction of square roots on the bottom to make it (x-4)(x+4) Then, because there are factors of (x+4) on the top and bottom, cancel them out to make it 7/(x-4)
Im guessing restrictions are the values x cannot be. So you take the denominator factors of (x+4)(x-4) and set them equal to zero. x+4=0 and x-4=0.
so x cannot =4, and -4
Hope this helps you answer the next ones!
Answer:
10,740 money does she ean.
Step-by-step explanation:
Given: Mrs Miller sells a house for 179,000.

hope that helps :)))
Answer:
D. {x:-8≤x<-5}
Step-by-step explanation:
x≥-8
x={-8,-7,-6,-5,-4,-3,-2,-1,0...}
x<-5
x={-6,-7,-8,-9,-0...}
Numbers equal to or less than -8 are also less than -5
Hope it helps ;) ❤❤❤
It would be 2:6, or 2 to 6.
I hope this helps :)
