Answer:
12
Step-by-step explanation:
Combining like terms is pretty simple. First, you would identify which terms are similar to what terms. For example, you can't combine two terms that aren't similar like 2x and 3y. It would have to be 2x and 3x to combine. Next, be sure to add/multiply/subtract/divide/etc. the terms. For example, if you had the problem 2x + 4x + 3y, you would combine the "x" terms and the resultant problem would be 6x + 3y. Hope this helped :)
Answer:
a = -4

2 = 3 + a/4
-1 = a/4
-4 = a
If 64 is a perfect cube the length of each edge of the block can be found. The edge length of a cube is: 4cm.
<h3>Edge length of a cube</h3>
Given:
Volume of cube=64cm³
Hence:
Volume of the cube = a³
Volume of the cube, a³= 64 cm³
Using this formula
Cube edge length =∛(side)³
Let plug in the formula
Cube edge length =∛(64cm³)
Cube edge length=4cm
Therefore if 64 is a perfect cube the length of each edge of the block can be found. The edge length of a cube is: 4cm.
