<em>Answer:192.53</em>
<em>Step-by-step explanation:</em>
<em> You just Add:</em>
$82.53+$110.00=192.53
Your answer is: 192.53
Answer is 512 cu.ft.
Volume of a cube is length x width x height
So 8 x 8 x 8 = 512
<u>Answer-</u>

<u>Solution-</u>
Given the two polynomials are 
So their product will be,

Distributing the Parentheses,

Applying minus-plus rules,

Simplifying further,

Multiply first example by 3 and subtract by second example, you will get the following:
3*(5x + 2y) = 3*22 => 3*5x + 3*2y = 66 => 15x + 6y = 66
now subtraction:
(15x + 6y) - (-2x + 6y) = 66 - 3
15x + 6y + 2x - 6y = 63
15x + 2x + 6y - 6y = 63
17x = 63
x = 63/17 ≈ 3.705..... and as it says to round to the nearest tenth our answer would be: x = 3.7
