You can use the distibutive property by breaking apart the bigger number (38) into 30 and 8. Now, you can do: (9 x 30) + (9 x 8)
I hope this helps!!!

Answer: C) tan(pi/56)
=============================================
Explanation:
I recommend using a trig identity reference sheet. The specific identity we will be using is
What we are given is in the form with A = pi/7 and B = pi/8
A-B = (pi/7)-(pi/8)
A-B = pi(1/7-1/8)
A-B = pi(8/56 - 7/56)
A-B = pi*(1/56)
A-B = pi/56
Therefore,
Mahmoud will have to work 21.52 hours to buy the game.
<h2><u>
Working hours</u></h2>
Since Mahmoud is a school student who just started working during the weekend, and he earns $ 14 per hour and he would like to buy a game that costs $ 80 which will have a 13% tax applied to it upon purchase, and Mahmoud would like to buy the game but only if he is able to save 30% of the money he will make, to determine how many hours would Mahmoud have to work the following calculation must be performed:
- 14X x 0.3 = 80 x 1.13
- 14X x 0.3 = 90.4
- 14X = 90.4 / 0.3
- X = 301.33 / 14
- X = 21.52
Therefore, Mahmoud will have to work 21.52 hours to buy the game.
