Check the picture below.

so the pyramid is really just 4 triangular faces with a base of 8 and a height of 5 and an 8x8 square at the bottom.

\stackrel{\textit{\large Areas}}{\stackrel{base}{(8\cdot 8)}~~ +~~\stackrel{4~triangles}{4\left[\cfrac{1}{2}(8)(5) \right]}}\implies64+20\implies 84

Please help me with this question! i will give brainiest if correct! (if you show me how to lol i have no idea how)
Nitella [24]

Answer:

  • y(2x² + y) / x(5y² - 6x)

Step-by-step explanation:

<u>Simplify the numerator:</u>

  • 1/x² + 2/y =
  • y/(x²y) + 2x²/(x²y) =
  • (2x² + y)/(x²y)

<u>Simplify the denominator:</u>

  • 5/x - 6/y² =
  • 5y²/(xy²) - 6x/(xy²) =
  • (5y² - 6x) / (xy²)

<u>Simplify the fraction:</u>

  • (2x² + y)/(x²y) ÷ (5y² - 6x) / (xy²) =
  • (2x² + y)/(x²y) × xy² / (5y² - 6x) =
  • y(2x² + y) / x(5y² - 6x)

What is the solution to the equation 8 - 2b = -2/3(12b + 6)?
Delvig [45]
<span>8 - 2b = -2/3(12b + 6)
8 - 2b = -8b -4
8 + 4 = -8b + 2b
12 = -6b
b = -12/6
b = -2

So, your final answer is b = -2</span>
