y represents the total amount Scott spent.
The question tells us the tote bag costed Scott 4 dollars; this is represented by 4 in the equation.
That leaves the 2x. The question tells us each book cost 2 dollars. The amount of money Scott spends on books depends on how many books he buys; this number is represented by x in this equation.
Answer:
The amount of books Scott bought.
Answer:
(x + 3)² = 14
Step-by-step explanation:
x² + 6x - 5 = 0
Add 5 and 9 on both sides.
x² + 6x + 9 = 14
Factor left side.
(x + 3)² = 14
Take the square root on both sides.
(x + 3) = ±√14
Subtract 3 on both sides.
x = -3 ±√14
The answer is 8.
half of 16 is 8
