Answer:x+12
Step-by-step explanation:
Answer:
66.7%
Step-by-step explanation:
The number of seedlings planted is 6, while the number of seedlings that survived the winter is 4. Therefore the percentage of seedlings that survived can be gotten using the formula:
Percentage of seedlings survived = (survived seedlings / total seedlings planted) * 100%
Therefore substituting values gives:
Percentage of seedlings survived = (4 / 6) * 100% = 66.7%
I believe it would be $87.51 not positive though.
Answer:
2x² + 3x - 1 - 5/(5x +2)
Step-by-step explanation:
2x² + 3x - 1

5x + 2 | 10x³ + 19x² + x - 7

| 15x² + x
| <u>- 15x² - 6x </u>
| - 5x - 7
| <u> 5x +2</u>
| - 5
2x² + 3x - 1 - 5/(5x +2)
Use the definition of absolute value.
• If 4x + 3 ≥ 0, then
|4x + 3| = 15
4x + 3 = 15
4x = 12
x = 3
• Otherwise, if 4x + 3 < 0, then
|4x + 3| = 15
-(4x + 3) = 15
4x + 3 = -15
4x = -18
x = -9/2
Then the solutions are {-9/2, 3}.
