Solve for x.

8x2−3=2

x=±10√4

x=±10√2

x=±5√2

x=±5√4

8x^2 = 5

x^2 = 5/8

x = sqrt(5/8)

x = sqrt(40)/8

x = 4(sqrt 10)/8

x = + sqrt 10/2

answer is b

Step-by-step explanation:

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
