I think you need to add them up and u will get 27
Answer:
-5/8h + 7
Step-by-step explanation:
First you need to combine like terms (1/8h and -3/4h)
So 1/8h - 3/4h is -5/8h
Then we have our 7 left over
So the answer is -5/8h + 7
Answer:
Surface area:


Volume :

Neither:



Step-by-step explanation:
Surface area of the cuboid:
The Surface area of the cuboid = 2(lb) +2(bh) +2(hl)
Where
l =length of the cuboid
b = Breadth of the cuboid
h = height of the cuboid
So ,
The surface area will be
SA = 
SA = 
SA =
SA = 
SA = 432
Volumes of the cuboid:

Volume = 
volume = 576
The answer is 28. 7x2=14 and then 14x2=28. Remember PEMDAS
(x+2)^2
This can be rewritten as:
(x + 2)(x + 2)
Multiply everything in the second parenthesis by x.
x^2 + 2x
Multiply everything in the second parenthesis by 2.
2x + 4
Add these equations together.
x^2 + 2x + 2x + 4
Combine like terms.
x^2 + 4x + 4
Hope this helps!
