Don't get what................................................
B) The symbol means less than OR equal to.
E) The symbol means more than OR equal to.
F) The symbol means equal to.
Since is addition you do the opposite and subtract 12 from 12 and -5 then 12 cancels out and -5-12=-17
Equation for this problem: Total 3 cubed / (L x W)
So 18.5cm x 15cm = 277.5 is the product of L and W. Now you need to devide the total by 277.5 which is 14. So the aquarium is 14 cm deep.
x=0
because you must
determine the undefined range
write all numerators above the common denomonator
multiply the parenthesis
collect the alike terms
remove parenthesis
eliminate the opposites collect the like terms
set the numerator equal to 0
divide both sides by 6
check if thesolution is the defined range
if so then you would find your answer X=0
