The answer for the first question would be 3952+3952 =7903
N/2 -7 = -6
add 7 to both sides;
n/2 -7+7 = -6+7
n/2 = 1
multiply both sides by 2 ( or divide by 1/2 ) in order to get n by itself.
n/2 * 2/1 = 1 * 2/1
n = 2
To do this, you’ll have to utilize the formula for volume.
Volume = length•width•height
V = 12•6•4
V = 12•24
V = 288 cm^3
** Remember that volume is always cubed.
