There are 6 surfaces on a rectangular prism . 3 pairs of equal area.
Surface area 2wl + 2hw + 2 hl where h = height, w = width, l = length.
So inserting the given values:-
442 = 2*w*11 + 2 *8* w + 2*8*11
442 = 22w + 16w + 176
38w = 442-176 = 266
w = 7
width = 7 feet
(3x+1)(4x-1)
3x+4x=7x
1-1=0
So
(3x+1)(4x-1) = 7x
I hope this helped and was right, have a nice day
