Answer:
B)
Step-by-step explanation:
(2x^3+x^2-4x)-(9x^3-3x^2)
2x^3-9x^3+x^2-(-3x^2)-4x
-7x^3+x^2+3x^2-4x
-7x^3+4x^2-4x
Answer:
A and B
Step-by-step explanation:
using the law of exponents
•
=
, hence
=
→ A
note that (- 3)² = 9 = 3², hence
= (3²)³ =
→ B
5/9 (fraction simplified)
let f=1
then
1^2+3(1)
=5
2(1)-1(5+1)(3)=19
hope this is the answer plz mark brillent thank you my friend
