Answer 1

Question 11
You seem to be missing a number from your equation

Question 12
-7(3n + 8)
= -21n - 56

Question 13
3x + x = 15 - 3
4x = 12
x = 12/4
x = 3

Question 14
7x - 12 + 4x - 4
= 11x -16

Question 15
5x - 4x + 2 = 2
x = 2 - 2
x = 0

Question 16
You did not write the equation

Question 17
-3x - 8x = 108 - 9
-11x = 99
x = 99/-11
x = -9

Question 18
The question seems incomplete, please double check it

Question 19
-0.07y + 0.14(100 - y) = 0.04y
-0.07y + 14 - 0.14y = 0.04y
-0.21y + 14 = 0.04y
14 = 0.04y + 0.21y
14 = 0.25y
y = 14/0.25
y = 56

Question 20
Once again, your equation is missing data

Question 21
-10.1q + 1 = -95.8 - 1.3q
1 + 95.8 = 10.1q - 1.3q
96.8 = 8.8q
q = 96.8/8.8
q = 11

Question 22
-6(8r + 3) + 10(10r + 3)
= -48r - 18 + 100r + 30
= 52r + 12

Question 23
numerical coefficient of (-8x) = -8

Question 24
-y = 7
y = 7*-1
y = -7

Question 25
8x + 6(-2x - 2) = -10 - 6x
8x - 12x - 12 = -10 - 6x
-4x - 12 = -10 - 6x
-4x = -10 - 6x + 12
-4x + 6x = -10 + 12
2x = 2
x = 2/2
x = 1

Answer 2

For increasing cubic binomials the final formula is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^one million + 3*a^one million*b^2 + b^3 on your case, a is x and b is -y^5 So (x - y^5)^3 = x^3 + 3*x^2*(-y^5)^one million + 3*x^one million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D

Answer 3

(6x - 9) = 6(x - ) + 9
6x-9=6x-6+9
0=6
