a) let the width be a letter i.e. any letter of the alphabet, it doesn't matter although preferably w. b) w+3 for the new width, 2w+3 for the new length c) new width is 2+3 new length is 4+3, multiply together for the new area
n=m/M n=117/22.99+35.45
1) (cos^2x+1+2sinx+sin^2x)/cosx(1+sinx) = 2+2sinx/cosx(1+sinx) = 2(1+sinx)/cosx(1+sinx) = 2/cosx = 2secx i'm going to assume you know the identities i.e. cos^2x+sin^2x=1 2) (cosx x cosx/sinx)/-sinx = cos^2x/sinx/sin^2x = cos^2x/-sin^2x = -cot^2x
3x+7y=-5 (i) 4x-3y=8 (ii) (i)x 4: 12x+28y=-20 (iii) (ii)x 3: 12x-9y=24 (iv) (iv)-(iii): -37y=44 y=-44/37 subs y into (i): 3x+7(-44/37)=-5 3x= -5+308/37 x=148/37
They are all correct
