Answer:
2⁴
Step-by-step explanation:
4² would be 4x4 not 2x2x2x2
2x2x2x2 would be 2⁴.
Answer:
Volume =
cubic inches
Step-by-step explanation:
A cube is the 3D version of a square. Since one side length is x inches, all the other side lengths are same, x inches each.
We know,
Volume = area of base * height
THe base is a square and the area is side * side. We know each side is x, so we have:
Area of Square = Area of Base = x * x = 
Now, we know height is also same side length, x, thus the volume becomes:
Volume = area of base * height
Volume = 
We add the exponents when we have same base multiplied, so the expression for volume becomes:
Volume =

18 - h = 13 when h = -5
18 - (-5) = 13
18 + 5 = 13
23 = 13
False, h would need to equal +5
Hope this helps! ;)
It would be what is 20% of 70. x = 20/100 x 70 = 14
20% of 70 is 14
