Question

hay que calcular los perímetros de los siguientes polígonos ayuda pliss​

Answer 1

Explicación paso a paso:

1)

$p = 2( {2x}^{2} + 3y + 4) + 2( {4x}^{2} + 2y + 5) \\ p = {4x}^{2} + 6y + 8 + {8x}^{2} + 4y + 10 \\ p = 12 {x}^{2} + 10y + 18$

2)

$p = 5(3y + 2) \\ p = 15y + 10$

3)

$p = 2(4y + 3) + 5y + 8 + 3y + 4 \\ p = 8y + 6 + 8y + 12 \\ p = 16y + 18$

4)

$p = {4x}^{2} + 5y + {2x}^{2} + 3y + {5x}^{2} + 8y \\ p = 11 {x}^{2} + 16y$

5)

$p = {6x}^{2} + 3 + {9x}^{2} + 5 + {10x}^{2} + 8 \\ p = 25 {x}^{2} + 16$

6)

$p =4 ( {5x}^{3} + 2y) \\ p = 20 {x}^{3} + 8y$
