I think you are supposed to make the fraction equivalent so you know that 27/9 is 3, so you would do the same thing whatever number is supossed to be under 17 needs to equal to 2 when divided by 9. So you should probably know that 3 * 9 is 18 so x needs to be a number that when subtracted by 5 gives you 18. So x=23. Hope this is right and it helps!

Answer:
V = ( 2 +H ) × ( 1 +H ) × H = (2 + 3H + H² ) unit³
Step-by-step explanation:
according to question :
Let the Height be = H unit
The measure of width = (1 inch + H) unit
The measure of length = 1 inch + width =( 1 inch + 1 inch + H) unit = (2 + H) unit
So, the volume V = Length × width × Height
Or, V = ( 2 +H ) × ( 1 +H ) × H = (2 + 3H + H² ) unit³ Answer
