4y = - 7 ( divide both sides by 4 )
y = - 
Answer: 48 cubic units
Step-by-step explanation: length x width x height
8 x 2 x 3 which equals 48
First, factor the expression on the top. What two numbers add to get 8 and multiply to 15? 5 and 3! so the top expression factors to (x+3)(x+5). You can cancel the x+3 from the denominator and end up with x+5. Make sense?
