C
length= 10 cm
width= 4 cm
height= 2 cm
10*4= 40
40*2= 80
If I calculated correctly, I believe the answer is B
Using a calculator hit 2nd then x^2 and the number you want then enter
I'm guessing you're trying to simplify the equation since there is no other information lol
[(2x+y)-3]
So basically when you are trying to simplify equations you have to add the same variables together (In this case X & Y) But since there are no alike variables there really is nothing to add
So your answer would be 2x+y-3
Hoped this helped
