For this case what you can do is factorize the <span>polynomial equation</span>, which would be left like follows
x ^ 3 + x ^ 2 + 9x + 9 = 0
(x + 1) (x ^ 2 + 9) = 0
Resolving, we have that the missing root is
x = -1
Answer
x=-1

Answer:
10x−31
Step-by-step explanation:
Let's simplify step-by-step.
10x+9−40
=10x+9+−40
Combine Like Terms:
=10x+9+−40
=(10x)+(9+−40)
=10x−31
Hope this helps and can you please give me brainliest ;-)
Answer:
Step-by-step explanation:
3n+15=75
three times a number is 3n. +15 is 15 more.
3n+15=75 subtract 15 from both sides to get the 3n alone
3n=60 divide by 3 to get the n by itself
n=20
Answer:
Step-by-step explanation:
We want to solve 
given that 
is acute.
We take tangent inverse of both sides to get:
Now set your calculator to degree mode and evaluate 
to obtain:
To one decimal place, we have;
