A. x doesnt equal - 4, -3
B. x doesnt equal 7, 0
C. x doesnt equal -4, 0
D. x doesnt equal 7, -3

Answer 1

basically you never want to multiply or divide by zero so the restriction is the value that would create that situation.

Answer 2

hope your visits were fine.
the original is not clearly written. can you use the "draw" below and write it out ?

Answer 3

\[\frac{ x - 7 }{ x + 4} \div \frac{ x }{ x +3 }\]

Answer 4

\[\frac{ x-7 }{ x+4 }\times \frac{ x+3 }{ x }\]
restrictions are\[x+4\neq0,x \neq-4~and~x \neq0\]
