Answer:

11700 mm²

Step-by-step explanation:

Vertical height between the centres of top and bottom circles

sqrt[(2×28)² - 28²]

= 28sqrt(3)

Width of the rectangle

= 4×28

= 112

Length of the rectangle

= 28sqrt(3) + 2(28)

= 56 + 28sqrt(3)

Area = 112 × (56 + 28sqrt(3))

= 11703.71133 mm²

What is 3x^2-2n-5=0<br> please help me!!!
expeople1 [14]
The answer to your question is: 
It is a quadratic equation in 'x', with 'n' mistakenly typed in the second term..

Although you didn't ask for the solutions to the equation, I'm already here
so I might as well go through it and find them:

<span><u>3x² - 2x - 5 = 0</u></span>

In terms of the generic quadratic formula:
A = 3
B = -2
C = -5

Plug those into the quadratic formula, and you discover that

<u>x = -1</u>
and
<u>x = ⁵/₃</u>
