We have that
-7x-60=x²<span>+10x
</span>x²+10x+7x=-60
x²+17x=-60
(x²+17x+8.5²)=-60+8.5²
(x+8.5)²=12.25
(+/-)(x+8.5)=√12.25--------> (+/-)(x+8.5)=3.5
(+)(x+8.5)=3.5------> x=-5
(-)(x+8.5)=3.5------> x=-12
therefore
(x+5)*(x+12) is equivalent to -------> -7x-60=x²+10x
the answer is
(x+5)*(x+12)

Answer:
The net profit per bike is 150-40= 120. Hence to break even, the store needs to profit more than the operating cost of the store. 3840/ 120= 32. The store needs to sell 32 bicycles each month to break even.
Answer:
2.4%
Step-by-step explanation:
Total amount of payments:
5 years * 12 months/year * $78.40/month =
= $4704.00
Amount of interest paid in 5 years:
$4704 - $4200 = $504
Amount of interest paid in 1 year:
$504/5 = $100.80
Annual percent rate of interest:
$100.80/$4200 * 100% = 2.4%
Answer: 2.4%
