Question

below simplify and calculation with explanation

Answer 1

Answer:

sides of the triangle =

3xy - 4x^2y , 4xy^2 - 3x^2y , 2xy^2 - 2xy

x = 2 and y = -1

=> 3xy - 4x^2y

=> 3(2)(-1) - 4(2)^2(-1)

=> -6 + 16 = 10

=> 4xy^2 - 3x^2y

=> 4(2)(-1)^2 - 3(2)^2(-1)

=> 8 + 12 = 20

=> 2xy^2 - 2xy

=> 2(2)(-1)^2 - 2(2)(-1)

=> 4 + 4 = 8

perimeter of a triangle = S + S + S

=> 10 + 20 + 8 = 38 cm

therefore the perimeter of the triangle = 38cm

i think this is the answer.............I hope this helps u

Answer 2

given,

X= 2

Y= -1

first side

$= 3xy - 4 {x}^{2} y \\ = 3 \times 2 \times ( - 1) - 4 \times 2 {}^{2} \times ( - 1) \\ = - 6 + 16 \\ = 10$

second side

$= 4 {x}^{2} y - 3 {x}^{2} y \\ = 4 \times 2 \times ( - 1) {}^{2} - 3 \times {2}^{2} \times ( - 1) \\ = 4 \times 2 \times 1 + 3 \times 4 \times 1 \\ = 8 + 12 \\ = 20$

third side

$= 2xy {}^{2} - 2xy \\ = 2 \times 2 \times ( - 1) {}^{2} - 2 \times 2 \times ( - 1) \\ = 4 + 4 \\ = 8$

therefore,

perimeter of the triangle

= 10+20+8

= 38

***please mention the required unit of the length of the sides of the triangle***
