Answer:  349 square units

============================================

Work Shown:

  • L = 5.5 = length
  • W = 5 = width
  • H = 14 = height

SA = surface area of rectangular prism

SA = 2*(L*W + L*H + W*H)

SA = 2*(5.5*5 + 5.5*14 + 5*14)

SA = 2*(27.5 + 77 + 70)

SA = 2*(174.5)

SA = 349

The surface area is 349 square units.

What is the value of A when we rewrite (32/5)^-2x as A^x​
defon

Answer:

(\dfrac{25}{1024})^x

Step-by-step explanation:

The given expression is :

(\dfrac{32}{5})^{-2x}

We need to rewrite it in the form of A^x.

We know that, (\dfrac{1}{x})^{-a}=x^a

So,

(\dfrac{32}{5})^{-2x}=(\dfrac{5}{32})^{2x}\\\\=(\dfrac{5^2}{32^2})^x\\\\=(\dfrac{25}{1024})^x

So, A=\dfrac{25}{1024}. Hence, this is the required solution.

Exact value: 9mm<br> approx value: 11mm
defon

Answer:

Your quality and RELIABLE 9mm pistol will typically run you $450–800 new with the large majority falling in the $500–600 range. Guns below that generally aren't worth purchasing outside of fun times. Guns above that generally have “extra” features that drive up the cost.
