Answer:
x = - 10 ± 
Step-by-step explanation:
y = (x + 10)² , or
(x + 10)² = y ( take square root of both sides )
x + 10 = ± ( subtract 10 from both sides )
x = - 10 ±
Answer:
Estimate: 700 Answer: 712
The computation shows that the number of pages is 320.
The number of pages read in this second day will be 120.
<h3>How to illustrate the information?</h3>
Fraction read on first day = 1/4
Fraction news on second day = 1/2 × 3/4 = 3/8
Fraction read on last day = 1 - (1/4 + 3/8) =3/8
The number of pages that the book has will be:
= 3/8 × x = 120
0.375x = 120
x = 120/0.375
x = 320
The number of pages is 320.
b. The number of pages read on this second day will be:
= 3/8 × 320
= 120
