The item would cost approximately $45. You can do this by taking the price of the item ($60) and multiply by the percent (25%). 60 x 0.25 = 15. That is the discount you would subtract from the item itself. Now you would take the original price ($60) and subtract the discount ($15). 60 - 15 = 45.
<span>To do that, you need to set it all to zero and factor:
x^2+8x+15 = 0
(x+5)(x+3) = 0
then put both those in parentheses chunks in their own equations
x + 5 = 0
x + 3 = 0
and then simplify
x = -5
x = -3
So the two points where the parabola crosses the x-axis are -5 and -3.</span>
Answer:
Step-by-step explanation:
b must not be an even number
2a>b
a+b>a
so b could be 3.1, 3.3, ......7.7
V would be 72
you need to multiple 3, 4, and 6.
doing it in separate steps could be easier
3 x 4 is 12. then 12 x 6 is 72
or if u have a calculator, just punch 3 x 4 x 6 which should give you 72
