Rewrite the expression below.<br><br> -2a( a + b - 5)+ 3 (-5a + 2b) +b (6a + b - 8)
Paul [167]

Answer:

b^2 + 4 a b - 2 b - 2 a^2 + -5 a

Step-by-step explanation:

Simplify the following:

-2 a (a + b - 5) + 3 (2 b - 5 a) + b (6 a + b - 8)

-2 a (-5 + a + b) = 10 a - 2 a^2 - 2 a b:

10 a - 2 a^2 - 2 a b + 3 (2 b - 5 a) + b (6 a + b - 8)

3 (2 b - 5 a) = 6 b - 15 a:

10 a - 2 a^2 - 2 a b + 6 b - 15 a + b (6 a + b - 8)

b (-8 + 6 a + b) = -8 b + 6 a b + b^2:

10 a - 2 a^2 - 2 a b - 15 a + 6 b + -8 b + 6 a b + b^2

Grouping like terms, 10 a - 2 a^2 - 2 a b - 15 a + 6 b - 8 b + 6 a b + b^2 = b^2 + (6 a b - 2 a b) + (6 b - 8 b) - 2 a^2 + (10 a - 15 a):

b^2 + (6 a b - 2 a b) + (6 b - 8 b) - 2 a^2 + (10 a - 15 a)

a b 6 + a b (-2) = 4 a b:

b^2 + 4 a b + (6 b - 8 b) - 2 a^2 + (10 a - 15 a)

6 b - 8 b = -2 b:

b^2 + 4 a b + -2 b - 2 a^2 + (10 a - 15 a)

10 a - 15 a = -5 a:

Answer:  b^2 + 4 a b - 2 b - 2 a^2 + -5 a

Who can solve this exercises pleaseeee i have a exam
Leona [35]

Answer:

Step-by-step explanation:

1) Two angles supplementary. So sum of two angles is 180

One angle  = x

Other angle = 2x

x + 2x = 180

3x = 180

x = 180/3 = 60

The angles are 60, 120

2)Two angles complementary. So sum of two angles is 90

one angle  = x

Other angle = x + 20

x +x +20 = 90

2x + 20 = 90

2x = 90- 20

2x = 70

x = 70/2 = 35

The angles are 35,55

3) one angle =x

Other angle = 3x - 20

x + 3x - 20 = 120

4x = 120 + 20

4x = 140

x = 140/4 = 35

The angles are 35,85

5) x + 4x -20 = 180

5x = 180 + 20

5x = 200

x = 200/5 = 40

x = 40

6) This sum is not clear only half is visible
