Answer:
5x² + 7x + 7
Step-by-step explanation:
Subtract 3 from 10
3x+5x²-x+7+5x
Subtract x from 3x
5x² +2x+7+5x
Add 2x and 5x to get the 7x
Here’s the work for the answer
- Multiply 2 with X (invisible one before the x)
-Multiply 2 with 3
It should be 2x - 6 = 24
Add 6 to 24
2x = 30
Divide by 2 on both sides
X=15
