1)
175 = 25(7)
√175=√25√7=5√7
2)
500 = 100(5)
√500 = √100√5 = 10√5

1) √175 = √(7 x 25) = 5 √ 7
2) √500 = √(5 x 100) = 10 √5 so c is the answer

1)
√175 = √(7 x 25) = 5 √7
2) √500 = √(100x5) = 10√5
So the answer is:
c) 10√5

c) 10√5
That's because √500 is around 22.37 and the √5 = 2.237. Multiplying 2.237 by 10 would yield the same result as √500.
Alternatively, I will try to prove it this way:
√500 = 10√5
(√500)²= (10√5)²
500 = (10)²x(√5)²
500 = 100x5
500 = 500
LHS = RHS, hence proven

1) Distance = Speed x Time So first 3 hours = 3r Next 5 hours = 5[r + 15] = 5r + 75 Therefore d = 3r + 5r + 75 = 8r + 75 2) I believe you can do this. Just substitute n as the number of items. Don't be lazy. 3) C = 2450 + 475x Calculate the cost yourself.
