Answer:
As i multiplied i got the answer like this
18x^3+6x^2+14x-72
8u2 ‒ 42u2 = - 34u2

Answer:
The answer is "5, 12, and 13".
Step-by-step explanation:
Please find the complete question in the attached file.
The right triangle is a triangle with only an angle of 90 degrees, as well as the go in the angle of 90 degrees, which is considered a hypotenuse.
The hypotenuse calculation square is equivalent to both the squared measures of the other two sides:

And even those squares do verify the equation:

So, it's a rectangular (right) triangle, with sides spanning 
<span>Here you go:
1) Applying (a + b)² = a² + b² + 2ab,
(cosx + cosy)² = cos²x + cos²y + 2cos(x)*cos(y) and
(sinx + siny)² = sin²x + sin²y + 2sin(x)*sin(y)
2) ==> (cosx + cosy)² + (sinx + siny)² =
= (cos²x + sin²x) + (cos²y + sin²y) + 2{cos(x)cos(y) + sin(x)sin(y)}
= 2 + 2{cos(x - y)} = 2[1 + cos(x - y)]
= 2*2cos²{(x - y)/2} [Multiple angle identity, 1 + cos(2A) = 2cos²A]
= 4*cos²{(x - y)/2} [Proved]</span>
Answer:
<em>.5, 3, 8.5</em>
Step-by-step explanation:
- Divide the minutes by 2 since 6 is half of 12.
- Half of 1 is .5 or

- Half of 6 is 3
- Half of 17 is 8.5
