Solve -6 4/9-3 2/9-82/9

Gala2k [10]

Answer: The final answer in proper fraction is 169/9

Step-by-step explanation:

Given the expression

-6 4/9-3 2/9-82/9

Firstly let us convert all mixed fraction to proper fraction to further simplify the expression

-58/9 - 29/9 - 82/9

We now have all terms in proper fraction, we can continue by finding the LCM which is 9

= (- 58-29-82)/9

= 169/9

Charles begins finding the volume of a trapezoidal prism using the formula a = one-half(b1 b2)h to find the prism's base area. a

Orlov [11]

The volume of the trapezoidal prism having side lengths x, (x+2), (x+4) and height of 2x is 2x³+6x² option first is correct.

<h3>What is volume?</h3>

It is defined as a three-dimensional space enclosed by an object or thing.

We know the volume of the trapezoidal prism can be given:

$\rm V=\frac{1}{2} (a+b)\times h \times L$

Where V = The volume of the trapezoidal prism:

Length of the trapezoid L = x

Top width a = (x+2)

Base width b = (x+4)

Height of the trapezoidal prism h = 2x

$\rm V=\frac{1}{2} (x+2+x+4)\times 2x \times x$

$\rm V=\frac{1}{2} (2x+6)2x^2\\\\\rm V= (2x+6)x^2\\\\\rm V= (2x^3+6x^2)$

Thus, the volume of the trapezoidal prism is $\rm (2x^3+6x^2)$
