Answer:
Step-by-step explanation:
To complete the square, we first have to get our equation into form.
First we add 16x to both sides:
And now we subtract 62 from both sides.
We now have to add to both sides of the equation. b is 16, so this value becomes .
We can now write the left side of the equation as a perfect square. We know that x+8 will be the solution because and .
We can now take the square root of both sides.
We can now isolate x on one side by subtracting 8 from both sides.
So our solutions are

Answer:
The amount of paper needed = 363.3 in²
Total amount of paper and plastic needed = 564.3 in
Step-by-step explanation:
As the diagram isn't given.
Consider a right cone shown in the ATTACHMENT.
where
r = 8 in
h = 12 in
First find the value of hypotenuse s by using Pythagoras theorem
<h3>Find Lateral Area:</h3>
The amount of paper needed to cover the candle is lateral area, which is given by:
<h3>Find Surface Area:</h3>
Total amount of paper and plastic is the surface area:
10 * 6 = 60 by the time Zach joins so 125-60 = 65
Now 6 (lexie) +7 (zach) = 13 (together) and 65/13 = 5.
6*5 = 30 and 7*5 = 35. 35+30 = 65
Your answer is 5.
Assume that 100% = 45 sales and 35% = X sales amount
You can create a ratio to help you solve for x
45 = 100%
x = 35 %
Which is equal to this fraction: (45/x) = (100/35)
Solving for X by cross multiplying and dividing by 100:
[(45)(35)] / 100 = X = 15.75 = 16 sales (rounded up)
You would need at least 16 sales to increase sales total by 35%
