Answer: It will take her 15 more hours to finish the book.
Step-by-step explanation:
25% : 5h
50% : 10h
75% : 15h
100% : 20h
It would take 20 hours to complete the book, but because she already read for 5 hours, it would be 15 to finish the book.

Idk if this helps but answer that i got was. ) X1=-1,x2=^33/2
$44.80 I could be wrong let me know
Let
x-------> √150
so
x²=150
we know that
10²=100
11²=121
12²=144
13²=169
x²=150
so
x< 13
x> 12
12< x<13
<span>the value of x is in the interval (12,13)
