Please help me out! Thank you so much in advance!

If E ax = 7 and [ by = 48, find the following values. K = 1 K = 1 n bk [ 2ak. 2 48' [ ( 2x + box ). E (2x -bx ) . E ( Dx - 42k ) K = 1 K = 1 K = 1 K = 1 K = 1 [ 2ax = K = 1 (Simplify your answer.) n bk k=1 (Simplify your answer.) E ( 2x + bx ) = K=1 (Simplify your answer.) I ( 2x - box ) - K=1 (Simplify your answer.) E (by - 42k) - K = 1 (Simplify your answer.)
