A) 2x - 7 = -1
Add 7 to both sides of the equation.
2x = 6
x = 3
Choice A is not the answer.
B) 3x + 8 = 1
Subtract 8 from both sides.
3x = -7
Divide both sides by 3.
x = -2.3 repeating
Choice B is not the answer.
C) 1/2x + 8 = 10
1/2x = 2
Divide both sides by 1/2.
x = 4
Choice C is not the answer.
By process of elimination, choice D is the answer.
D) 1/2(2x - 6) = -6
x - 3 = -6
Add 3 to both sides.
x = -3
Given:
The square base pyramid with height 3 cm and base edge 2 cm.
To find:
The volume of the square pyramid.
Solution:
Volume of a square base pyramid is:
...(i)
Where, B is the base area and h is the height of the pyramid.
Base is a square with edge 2 cm, so the base area is:

Where, a is the edge of the square base.


Putting
in (i), we get
Therefore, the volume of the given pyramid is 4 cm³.
I think it’s A not sure tho :|
Answer:
a= m<SQR
Step-by-step explanation:
1+2i
to find the midpoint you do it just like you did with rectangular coordinates,
add and divide by 2 the real component and the imaginary components.
