4.005 , 4.045 , 4.054 , 4.405 , 4.504
Answer: I think that it is the first one
The three lengths are 3x, 6x, 8x.
The perimeter of a triangle is the sum of all lengths:
3x + 6x + 8x = 520.
Solving for x,
17x = 520
x = 30.59 cm
So the three lengths are
3(30.59) = 91.77 cm
6(30.59) = 183.54 cm
8(30.59) = 244.72 cm
The difference between the two polynomials is 11x²3y³ - 4xy².
<h3>What is the Difference between the Polynomials?</h3>
The difference between two polynomials is the result you get by subtracting one from the other.
Thus:
= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)
= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y
= 11x²3y³ - 4xy²
