We can always do a prime factoring of it, and check
50 = 2*5*5
2*5²
a perfect square, so-called, is the resulting number of a squared value, well 50 is not the result of anything squared, is the result of 3 factors, in this case 2,5 and 5.
a perfect square will be something like say 64, or 144, because
64 = 8*8
8²
144 = 12*12
12²
Answer:
7) C
8) B
9) C
Step-by-step explanation:
7) sqrt[(8-8)² + (-5-7)²] = 12 units
8) y = 4x
9) y = 6 - x
I would go with C because if you do A then its all new students and thats one view D is the same. C seems like the best choice.
Answer =$388.75
25x.10= $2.50, 35x.15=$5.25, 350x.20=$70
$2.50+5.25+70=$77.75x5 days=$388.75
