Answer:
1,712,304 ways
Step-by-step explanation:
This problem bothers on combination
Since we are to select 5 subjects from a pool of 48 subjects, the number of ways this can be done is expressed as;
48C5 = 48!/(48-5)!5!
48C5 = 48!/43!5!
48C5 = 48×47×46×45×44×43!/43!5!
48C5 = 48×47×46×45×44/5!
48C5 = 205,476,480/120
48C5 = 1,712,304
Hence this can be done in 1,712,304ways
I think the answer is B.It is a space telescope
To make x^2 + 2x a perfect square we need to add the term { 2 / (2*1) }^2
which equals 1.
Add 1 to both sides: x^2 + 2x = 8
add 1 to both sides: x^2 + 2x + 1 = 8 + 1 (x + 1)^2 = 9
Take square root on both sides: x + 1 = +/- 3 x = +3 - 1 or x = -3 - 1 x = 2 or x = -4
Given:
Saving amount = $900
Cost of Laptop = $600
Cost of food = $60 every 2 weeks
Let x be the number of times Sara can withdraw money for food. The inequality would be:
60x + 600 <u><</u> 900
60x + 600 <u><</u> 900
<u> - 600 -600</u>
60x <u><</u> 300
<u>÷ 60 ÷60</u>
x <u>< </u>5
Sara can withdraw money 5 times or less for food.
