6x^2 + 4(x^2 - 1) =
6x^2 + 4x^2 - 4 =
10x^2 - 4 <===
Answer:
n > 10
n < 9
Interval notation:
(-∞, 9) U (10, ∞)
Step-by-step explanation:
2n + 7 > 27 or 3 + 3n < 30
-7 -7 -3 -3
2n > 20 3n < 27
÷2 ÷2 ÷3 ÷3
n > 10 n < 9
<--------- ----------->
<---------0--------0--------->
9 10
I hope this helps!
Yes it is a polynomial .
The degree of polynomial is 4 and there is no power as a fraction or negative integer
Answer:
b
Step-by-step explanation:
first, group the terms with the same power together and it would become (-9n⁵-4n⁵)+(n³-9n³)+(11n+6n). then, combine the terms in each group together which would get -13n⁵-8n³+17n as the answer
