Answer:
2x^3 +7x^2+3x-2
Step-by-step explanation:
3x^3 +7x^2 -x
- ( x^3 -4x +2)
------------------------
The first step is to line up the variables by degree
3x^3 +7x^2 -x
- ( x^3 -4x +2)
----------------------------
Then distribute the minus sign
3x^3 +7x^2 -x
- x^3 +4x -2
----------------------------
2x^3 +7x^2+3x-2
Answer:
The answer is A, ∠ABC is obtuse. We don't know if it's true or false.
Step-by-step explanation:
An open statement in mathematics is a statement where you don't know if it's true or false.
Answer:
![f(x) = -9.1](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-9.1)
Step-by-step explanation:
The midline is set on
, when the sine function is equal to zero, eliminating the effect from amplitude. The midline is a horizontal line. Hence, the equation of the midline is:
![f(x) = -9.1](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-9.1)
To know if there is a perfect square you gotta see if there is a minus sign before the second coefficient and when you square the second coefficient divided by 2 you should get the third coefficient
