X=-5/6 and x=5/6 hope I could help.
Well I would say multiply 16*4 to get 64 so unless you want to answer it, the answer is (-5*64) is your simplified equation. ()- is just to separate from the words
* - is multiply symbol. This is much more useful when using variables so your X variable don't get mixed up.
I got 155♀️ I don’t know cause I did PEMDAS and got 155
Answer:
-3x⁴ + 8x³ - 9x² - 7x - 9
General Formulas and Concepts:
Step-by-step explanation:
<u>Step 1: Define expression</u>
(5x³ - 3x⁴ - 2x - 9x² - 2) + (3x³ + 2x² - 5x - 7)
<u>Step 2: Simplify</u>
- Combine like terms (x³): -3x⁴ + 8x³ - 9x² - 2x - 5x - 2 - 7
- Combine like terms (x): -3x⁴ + 8x³ - 9x² - 7x - 2 - 7
- Combine like terms (constants): -3x⁴ + 8x³ - 9x² - 7x - 9
Answer:
2x = 3
Step-by-step explanation:
On the left, we have x+x = 2x.
On the right, we have 1+1+1 = 3.
The balance means the left is equal to the right:
2x = 3
