Answer:

36 g^2 + -60 g h + 25 h^2  thus: B

Step-by-step explanation:

Expand the following:

(6 g - 5 h)^2

(6 g - 5 h) (6 g - 5 h) = (6 g) (6 g) + (6 g) (-5 h) + (-5 h) (6 g) + (-5 h) (-5 h):

6×6 g g - 5×6 g h - 5×6 h g - 5 (-5) h h

6 g×6 g = 6×6 g^2:

6×6 g^2 - 5×6 g h - 5×6 h g - 5 (-5) h h

6×6 = 36:

36 g^2 - 5×6 g h - 5×6 h g - 5 (-5) h h

6 (-5) = -30:

36 g^2 + -30 g h - 5×6 h g - 5 (-5) h h

-5×6 = -30:

36 g^2 - 30 g h + -30 h g - 5 (-5) h h

-5 h (-5) h = -5 (-5) h^2:

36 g^2 - 30 g h - 30 h g + -5 (-5) h^2

-5 (-5) = 25:

36 g^2 - 30 g h - 30 h g + 25 h^2

g h (-30) + h g (-30) = -60 g h:

Answer:  36 g^2 + -60 g h + 25 h^2

How do you solve the problem and what is the answer?<br><br>-2 = g -9<br>​
pogonyaev

Answer:

Hey Dude ok so it's g = 7 Have a nice day!

Step-by-step explanation:Simplifying

-2 = g + -9

Reorder the terms:

-2 = -9 + g

Solving

-2 = -9 + g

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '-1g' to each side of the equation.

-2 + -1g = -9 + g + -1g

Combine like terms: g + -1g = 0

-2 + -1g = -9 + 0

-2 + -1g = -9

Add '2' to each side of the equation.

-2 + 2 + -1g = -9 + 2

Combine like terms: -2 + 2 = 0

0 + -1g = -9 + 2

-1g = -9 + 2

Combine like terms: -9 + 2 = -7

-1g = -7

Divide each side by '-1'.

g = 7

Simplifying

g = 7
