Question

Someone help me with the two math problems

Answer 1

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

Answer 2

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.
