Mathematics
1 answer:
SOVA2 [1]3 years ago
4 0

Answer:

r=\dfrac{31}{3}

Step-by-step explanation:

The problem says that G is any point lying on line segment DM. So,

DG = GM

We have, DG = and GM = 4r-28

Putting values in above equation

r +3 = 4r-28

Taking like terms together

r-4r = -28-3

-3r = -31

r=\dfrac{31}{3}

So, the value of r is \dfrac{31}{3}

What should be subtracted from -8xy + 2x^2 + 3y^2 to get x^2 + 2
Minchanka [31]

Answer:

x^2 - 8xy + 3y^2 - 2

Step-by-step explanation:

(-8xy + 2x^2 + 3y^2) - unknown = x^2 + 2

- unknown = x^2 + 2 + 8xy - 2x^2 - 3y^2

- unknown = -x^2 + 8xy - 3y^2 + 2

Unknown = x^2 - 8xy + 3y^2 - 2

Check:

(-8xy + 2x^2 + 3y^2) - (x^2 - 8xy + 3y^2 - 2)

= -8xy + 2x^2 + 3y^2 - x^2 + 8xy - 3y^2 + 2

= -8xy + 8xy + 2x^2 - x^2 + 3y^2 - 3y^2 + 2

= x^2 + 2
