We have that
x²<span>+2x=17
</span><span>Group terms that contain the same variable
</span>(x²+2x)=17
<span>Complete the square. Remember to balance the equation
</span>(x²+2x+1)=17+1

Rewrite as perfect squares

(x+1)²=18

x+1=(+/-)√18

x=(+/-)√18-1

x1=√18-1----> 3.24

x2=-√18-1----> -5.24


the answer is

the option 

<span>4.) 3.24, –5.24</span>

candy wants to have 600 copies of his resume printed. His local print shop charges $22.40 for the first 400 copies and $10 for e
goblinko [34]

Answer:

$44.94

Step-by-step explanation:

400+100+100 = 600

22.40 + 10 +10 = 42.40

(22.40 for the first 400 and 10 for each additional 100)

If tax is 6%, you can multiply the whole thing (42.40) by 1.06 to get the total amount of 44.94.


Why 1.06? If you think about it, tax is 6%. 6% is the same as 0.06. You pay 100% for the products, so with tax, it's the equivalent of 106%, or 1.06.
