2x^3+x^2-9x+6
Answer:
24 = x
Step-by-step explanation:
You use Pythagorean theorem. Since the normal equation is 
, you already have the 
and another side which can be 
or 
.
Because you have the hypotenuse and a side , your equation looks like this now: 
and when you solve for be you just subtract 
to get 24.
Answer:
$2.64
Step-by-step explanation:
Selling them at 5 cents each ($0.05), he could sell 1 dozen buttons for
12 * $0.05 = $0.60
As he bought them at $0.38 per dozen, the profit per dozen would be
$0.60 - $0.38 = $0.22
As 12 dozen is 1 gross, the profit per gross would be
12 * $0.22 = $2.64
Y=1.22x
y is the cost and x is kilometers driven. I got 1.22 by dividing 366 by 300 to find how it costs per kilometer.
Hi
We know that Area= length * width right?
So this is what we do.
Total area/length
25/54 / 5/9
You get the width to be 5/6
CHECK:
5/6*5/9=25/54
Hope this helps :)
