ii.4(x - 2) + 4(x - 3) + 3(x – 4)
iii. x(2 + 5x) + 10x2 – 5x(2x - 3)
iv. 3(a + 3) + 4(a + 2) + 5(a + 4)
v.a(3a + 4b) + b(3a + 4b)
please give this answer​

Answer 1

Answer:

$- 3x \times - 4 {x}^{2} {y}^{2} \times 5 \times 5 {y}^{3} \\ 300 {x}^{3} {y}^{3}$

$4(x - 2) + 4(x - 3) + 3(x - 4) \\ 4x - 8 + 4x - 12 + 3x - 12 \\ 11x - 30$

$x(2 + 5x) + 10 {x}^{2} - 5x(2x - 3) \\ 2x + 5 {x}^{2} + 10 {x}^{2} - 10 {x}^{2} + 15x \\ 5 {x}^{2} + 17x$

$3(x + 3) + 4(x + 2) + 5(x + 4) \\ 3x + 9 + 4x + 8 + 5x + 20 \\ 12x + 37$

$x(3x + 4y) + y(3x + 4y) \\ 3 {x}^{2} + 4xy + 3xy + 4 {y}^{2} \\ 3 {x}^{2} + 7xy + 4 {y}^{2}$
