Answer: ![2x^4+2x+10](https://tex.z-dn.net/?f=2x%5E4%2B2x%2B10)
Step-by-step explanation:
You need to remember the mulplication of signs:
![(+)(+)=+\\(-)(-)=+\\(-)(+)=-](https://tex.z-dn.net/?f=%28%2B%29%28%2B%29%3D%2B%5C%5C%28-%29%28-%29%3D%2B%5C%5C%28-%29%28%2B%29%3D-)
Knowing this, you can distributive the negative sign. Then you get:
![(-7x- 5x^4 + 5) - (-7x^4 - 5 - 9x)=-7x- 5x^4 + 5 +7x^4 + 5 + 9x](https://tex.z-dn.net/?f=%28-7x-%205x%5E4%20%2B%205%29%20-%20%28-7x%5E4%20-%205%20-%209x%29%3D-7x-%205x%5E4%20%2B%205%20%2B7x%5E4%20%2B%205%20%2B%209x)
Now you need to add the like terms. Then:
![=2x+2x^4+10](https://tex.z-dn.net/?f=%3D2x%2B2x%5E4%2B10)
Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:
![=2x^4+2x+10](https://tex.z-dn.net/?f=%3D2x%5E4%2B2x%2B10)
Answer:

ANSWER-the distance is (6,8)
if you set the equation up from 2-8=6 which is your x value and 4-12=8 is your y value it should also give you your Distance between the two points
Answer:
17= addition
18 = 27
Let's solve your equation step-by-step.
43x−4=5−x
Step 1: Simplify both sides of the equation.
43x−4=5−x
43x+−4=5+−x
43x−4=−x+5
Step 2: Add x to both sides.
43x−4+x=−x+5+x
73x−4=5
Step 3: Add 4 to both sides.
73x−4+4=5+4
73x=9
Step 4: Multiply both sides by 3/7.
(37)*(73x)=(37)*(9)
x=277
Answer:
x=277
