3x = 18 - 3 times girls = # boys = 18
x = 6 - # of girls in the class
Answer:
13). -2x³ + x² + 1 14). x + 10y - 10z 15). -2x³ + x² + 1
Step-by-step explanation:
13). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² - 3 + 4
= -2x³ + x² + 1
14). (3x + 4y - 3z) - (2x - 6y + 7z)
= 3x + 4y - 3z - 2x + 6y - 7z
= 3x - 2x + 4y + 6y - 3x - 7z
= x + 10y - 10z
15). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² + 4 - 3
= -2x³ + x² + 1

What are employees' benefits?</h3>
- Employee perks and benefits in kind are non-wage compensation provided to employees in addition to their regular income or salary.
- A "salary package" or "salary exchange" arrangement is one in which an employee exchanges salaries for some other type of compensation.
To find Lakisha's total job benefits:
If Lakisha's employer pays $2,150 in health insurance and $86 in life insurance per year, and she also gets $3,520 in paid time off per year, then Lakisha's total job benefits per year are equal to:
Total Benefits = Health Insurance + Life Insurance + Paid Time Off + Annual Gross Pay
- Total Benefits= $2,150+$86+$3,520+12($4,370)
- Total Benefits= $2,150+$86+$3,520+$52,440
- Total Benefits=$58,196
Therefore, Lakisha's total job benefits per year are (D) $58,196.
