What is the simplified expression for -3(2x- y) + 2y + 2(x+y)2
o 8x+y
o y-4x
0 7x-4x
0-4x-y

7y-4x.

Step-by-step explanation:

I think that the last 2 shouldn't be there and the third option should be 7y-4x or all the options are incorrect.

-3(2x- y) + 2y + 2(x+y)

= -6x+3y + 2y+2x+2y

= -6x+2x+3y+2y+2y

= -4x+7y.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
