Answer 1

Step-by-step explanation:

$\\ a) \\ (10 {x}^{2} + 14) + ( 9 {x}^{2} + 3) - 18 {x}^{2} - 6) \\ {x}^{2} + 11 \\ \\ b) \\ (29 {x}^{3} - 11x + 30 - (17 {x}^{3} - 8x - 22) + 37 {x}^{2} + 2) \\ 12 {x}^{3} + 37 {x}^{2} - 3x + 54 \\ \\ c) \\ 76 {x}^{2} - 54x + 31 - (26 {x}^{2} - 17x + 8) - (24 {x}^{2} + 3) \\ 26 {x}^{2} - 37 x + 20$

Answer 2

Answer:

a)(10x^2+14)+(9x^2+3)-(8x^2-6)

10x^2+14+9x^2+3-8x^2+6

11x^2+23

b)(29x^3-11x+30)-(17x^3-8x-22)+(37x^2+2)

29x^3-11x+30-17x^3+8x+22+37x^2+2

12x^3-3x+24+37x^2.

hope it helps you.
