2a+54=38 2a=38-54 2a=-16 a=-16/2 a=-8

2a 4 is the same as saying 2*a*4, so if you plug 2 in for a, this equals 16

If its 2a=8 then a= 4 If a=8 then a2=16 If 8=D then 8=====================================D

a + a + a - 2a = 3a - 2a = a

A = 36 mi2, h = 12 mi, b = ? mi A = (bh)/2, multiply by 2 to both sides 2A = bh, divide by h to both sides (2A)/h = b, substitute A and h respectively with 36 and 12 (2*36 mi2)/(12 mi) = b, simplify b = 6 mi
