Answer:
Step-by-step explanation:
V = x(14 - 2x)(18 - 2x)
V = (14x - 2x²)(18 - 2x)
V = (252x - 28x² - 36x² + 4x³)
V = 4x³ - 64x² + 252x
V' = 12x² - 128x + 252
0 = 3x² - 32x + 63
x = (32 ±√(32² - 4(3)(63))) / (2(3)
x = (32 ± √268) / 6
x = 8.06 inches, which we ignore as this would mean we have no material left at all in the 14 inch dimension.
or
x = 2.60488... 2.60 inches
Vmax = 0.60(14 - 2(2.60))(18 - 2(2.60)) = 292.86478... = 292.86 inches³
Given:
The equation is

To find:
The reason for second step.
Solution:
We have,

Using multiplication property of equality, multiply both sides by 3.

Using addition property of equality, add 4 on both sides.


Using division property of equality, divide both sides by 2.


So, the reason for second step is multiplication property (=).
Therefore, the correct option is D.
Answer:
1:2
Step-by-step explanation:
There are 18 nickles so that number is 18. When added together, there are 36 total coins. Since it states nickle to all coins, we replace <em>to</em> with a colon and replace the words with the related numbers.
18:36
like a fraction, ratios can be simplified. 18 is half of 36 so the ratio would go to 1:2. This means that 1 in every 2 coins is a nickle.
