AYE i just did the quiz i got you GIRL it's the first one, third and the last one
<h3>Answer:</h3>
- x = 5/6 in ≈ 0.83 in
- v = 125/108 in³ ≈ 1.16 in³
<h3>Explanation:</h3>
The width of the cardboard (in inches) will be 4x, and its length will be (5-4x) so the perimeter adds up to 10 in. Then the volume is the product of the area of the open ends (x²) and the length (5-4x).
The graphing calculator shows that volume is maximized when the value of x is 0.833, or 5/6 inch. The corresponding length is 5-4x = 5/3 inch, so the volume is ...
... v = (5/6)²×(5/3) = 125/108 . . . . in³
The corresponding decimal values of x and volume are ...
... x ≈ 0.83 in
... v ≈ 1.16 in³
Answer:
32
Step-by-step explanation:
40 = 100%
how many are 80% ?
well, 80% = 80× 1%
1% = 100% / 100
so, in our case
80% = 80×40/100 = 8×4 = 32
as a shortcut you consider a percentage x as a ratio factor of x/100 you multiply the 100% number with.
in our case
80% = 40 × 80/100 = 32
Answer: 
Step-by-step explanation:
1. By definition you have that the difference of squares is:

2. Given the polynomial:

You can identify that there are two terms whose signs are different and they are perfect squares.
3. Therefore, you have:

Six (6) less than (subtraction) six (6) times (multiplication) a number (n) is (=) 12.
6n - 6 = 12
To solve, add 6 to both sides
6n = 18 Dviide both sides by 6
n = 3
