Answer:
ok
Step-by-step explanation:
<span>25, 36, 49, 64....
5^2, 6^2, 7^2, 8^2......
so at nth term, it is (n+4)^2
100th term = (100+4)^2 = 104^2 = 10816</span>
Answer: 7x^2+21x+14
Step-by-step explanation:
(7x+7)(x+2)
Multiply each term in the first parentheses by each term in the second parentheses (FOIL)
7x×x+7x×2+7x+7×2
↘ ↙
7x×x calculate product
7x^2+7x×2+7x+7×2
↘ ↙
7x×2 calculate product
7x^2+14x+7x+7×2
↘↙
7×2 multiply numbers
7x^2+14x+7x+14
↘ ↙
21x collect like terms
7x^2+21x+14 is your end result.
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.
