The answer is 4a - 12 so b.
Take half of the coefficient on the x term
X=6....6(6-6)=4(6=6) 6(0)=0....0=\=4 6=6
It doesnt differ lets take
10 = 6 + 4
multiply thru by a negative and flip the sign
-10 = -6 - 4
flipping an equals sign about seems redundant, but the process works nonetheless <span>having two separate rules for solving inequalities and equalities seems pointless

C
length= 10 cm
width= 4 cm
height= 2 cm
10*4= 40
40*2= 80
