Answer 1

Ответ:I apologize for my previous response. Let me try to interpret and solve the equations you provided:

65.

1) a + 1 - 6^2 / 2

This equation can be simplified as:

a + 1 - 36 / 2

a + 1 - 18

a - 17

2) 2) - + X 2 2 2x x-4 12n-5

This equation is not clear and seems to have some missing variables and operators. Could you please provide more information or clarify?

66.

1) 2 n² - 49 1+b' 1 x +3 5x-2. 2; 16-x + 6 7-n 3 2a +.

Again, this equation is not clear and seems to have missing variables and operators. Please provide more information or clarify.

67.

1) a + 2 (a+2)²

This equation can be expanded as:

a + 2(a^2 + 4a + 4)

a + 2a^2 + 8a + 8

2a^2 + 9a + 8

3) ²

This equation is incomplete and doesn't make sense. Please provide more information or clarify.

4) 3) 4) 5+ p 2 p - 36 2x x-4 Р 6+ p 5x-2 2 x-16 c²-8 16c-2c³ 2c +3 9-4c² 21 +1 1-9y² - ; y 3y-1 a 4

Once again, this equation is incomplete and doesn't make sense. Please provide more information or clarify.

2) (3a + 1)² + 34+1 (3a+1)

This equation can be simplified as:

(3a + 1)^2 + 35(3a+1)

(3a + 1)(3a + 1) + 35(3a+1)

(9a^2 + 6a + 1) + (105a + 35)

9a^2 + 111a + 36
