Answer:
12x + 2
Step-by-step explanation:
12 is multiplyed by both the x and the (1/6) since it is outside the equation.
so 12 times x = 12x since we dont know what x is
and 12 times (1/6) = (12/6) = 2
I belive it is (40x10)+(40x7)+(3x10)+(3x7)
.
DC = 16 and
DB = 30 so
CB = 14
DB = 30 and
EB = 49 so
EB = 19
