Answer:
3. 3 and 4
4. 5 and 6
5. x=-3
Step-by-step explanation:
3. [tex]\sqrt{11}[/tex] is between 3 and 4 because 3 is equal to [tex]\sqrt{9}[/tex] and 4 is equal to [tex]\sqrt{16}[/tex]. Since 11 is in between 9 and 16 this is the answer.
4. Same thing, except since 5 is [tex]\sqrt25}[/tex] and 6 is [tex]\sqrt{36}[/tex], and 34 is between 25 and 36
5. The equation is -31=4x-19, and we need to isolate x
First, add 19 to both sides
[tex]4x=-12[/tex]
And next divide both sides by 4 to get
[tex]x=-3[/tex]
