Answer:
Step-by-step explanation:
For a start simplify each of the roots:
Now simplify the expression in steps:
Answer: a)
Step-by-step explanation:
We know that the volume of an oblique pyramid is given by :-
If the volume of an oblique pyramid with a square base is V units³ and the height is h units.
Then, we have
Multiply 3 on both sides , we get
Divide both sides by h , we get
i.e.
Hence, the expression represents the area of the base of the pyramid =
Hence, the correct answer is a) 3 v/h units^2
The seven is in the ones place because its the only number there
X-y=-1
x+y=5
y=x+1
x+x+1=5
2x+1=5
2x=4
x=2
y=x+1
y=2+1
y=3
