Step-by-step explanation:
4 to 9 is 5 hours,the total hours for the week is 32.5 hours
7x² + 20x - 3 = 0
x = <u>-(20) +/- √((20)² - 4(7)(-3))</u>
2(7)
x = <u>-20 +/- √(400 + 84)</u>
14
x = <u>-20 +/- √(484)
</u> 14<u>
</u>x = <u>-20 +/- 22
</u> 14<u>
</u>x = <u>-20 + 22</u> x = <u>-20 - 22
</u> 14 14<u>
</u>x = <u>2</u> x = <u>-42
</u> 14<u /> 14
x = ¹/₇ x = -3<u />
