5(^ 1/5 +-4) 2(-4)(-0.8)^ 2

How do i do this activity, is appreciated

Which expression is equivalent to 3^3 + 2^2?

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
