b = 9

c = x

a² + b² = c²

The height of a square prism is 3n + 1. The volume of the prism is 3n³ + 13n² + 16n + 4. What is the area of the square base of
EastWind [94]
If s is the side of the square base, the area of the square base is s^2.
The volume of the square base is,
V = (s²) (h)
s² = V/h
s² =  3n³ + 13n² + 16n + 4 / <span>3n + 1
You can do this division by factoring, synthetic division, or by plain division.
Factoring out 3n + 1 from the numerator gives you:
</span>s² = (3n + 1)(n² + 4n + 4) / 3n+1
s² = n² + 4n + 4

Therefore, the area of the square base is <span>n² + 4n + 4.</span>

What is 3 divided by 2/3 x 3? <br><br> please show work!
IgorC [24]

<u>Answer:</u>

<em>The correct answer is 1 1/2</em>

<u>Step-by-step explanation:</u>

<em>First, We need to find out the sum of 2/3  x 3, change 3 into a fraction if you want</em>

<em>3x2=6 and 1x3 is 3, So 2/3 x 3 is 6/3 or 2</em>

<em>Next, divide 3 by 2, change to fractions if needed</em>

<em>Remember keep, change and flip, flip 2/3 to 1/2</em>

<em>Then, you multiply 3/1 and 1/2 3x1=3 1x2=2</em>

<em>Finally divide 3 by 2. 3  ÷ 2 is 1 1/2</em>

<em>I hope this helped!</em>
