Answer:
He multiplied the denominators incorrectly
Step-by-step explanation:
we know that
The volume of a rectangular prism is given by the formula
V=LWH
we have
L=3/4 ft
W=5/1 ft
H=1/2
substitute
V=(3/4)(5/1)(1/2)= 3x5x1= 15
₋₋₋₋₋₋₋₋ ₋₋₋₋ ft³
4x1x2= 8
therefore
He multiplied the denominators incorrectly
(1/25)/74=
(1/25)*(1/74)=
1/1850
You are trying to find how much younger Kaylee is than Lylah.
You would subtract her age from Lylah's.
45-18= 27
Kaylee was 27 years younger than Lylah.
I hope this helps!

Example: ![1x+2y+3z+4a+5x+6y+7z+8+9](https://tex.z-dn.net/?f=1x%2B2y%2B3z%2B4a%2B5x%2B6y%2B7z%2B8%2B9)
We can see that there is more than one number with the variable x, therefore, we say they're ''like terms'' and because of that they can be summed. We do this with all of the other numbers with similar variables. If no numbers with similar variables are left, like 4a, you don't do anything but write them as they are. You can also see that 8 and 9 can also be summed because neither of them has a variable, therefore they're similar.
In this step, you just do the operation with the numbers and keep the same variable.
![(1x+5x)+(2y+6y)+(3z+7z)+4a+(8+9)](https://tex.z-dn.net/?f=%281x%2B5x%29%2B%282y%2B6y%29%2B%283z%2B7z%29%2B4a%2B%288%2B9%29)
![(6x)+(8y)+(10z)+4a+(17)](https://tex.z-dn.net/?f=%286x%29%2B%288y%29%2B%2810z%29%2B4a%2B%2817%29)
since there are not more numbers similar in variables, this operation is done.
![6x+8y+10z+4a+17](https://tex.z-dn.net/?f=6x%2B8y%2B10z%2B4a%2B17)
