Answer:
13. x=0, x= -4
14. NO EXCLUDED VALUE
Step-by-step explanation:
13. set the denominator to equal to 0 = x^2 + 4x = 0
factor the expression x × (x + 4) = 0
separate into possible cases = x = 0 and x = -4
state the excluded value = x = 0 and x = -4
14. set the denominators equal to 9 = x^2 +81 = 0
the statement is false for any value if x = x € ℝ
Btw, you can just use photo math, its an app you can download on the app store. Just take a pic of the math problem and it'll show you the answer AND how to do it.
