Answer:
⇒ 40 cm
Step-by-step explanation:
Given:
Height of cubes used by Nelson = 8 cm
Height of cubes used by Andrews = 10 cm
Solution:
Nelson made a stack of cubes where the height of the cubes is 8 cm, so the multiplication of the cube height is.
⇒
Similarly Andrew also made a stack of cubes where the height of the cubes is 10 cm, so the multiplication of the cube height is.
⇒
We can see the shortest same height of the both stack is 40 cm.
Therefore, 40 cm is the shortest possible stake height for both.

Your answer is c because 70and 64 tells you the answer
-5 is essentially -1·5
Order of operations says to do exponents first, so without parentheses -5², you would square first then multiply by -1, leaving you with an answer of -25.
However, parentheses comes before exponents in order of operations, so with parenthesis (-5)² would be 25.
