The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.
C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.
D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.

Answer:
Cube
Step-by-step explanation:
The cubed root of 8 = 2 because 2³ = 8.
So 8 is perfect cube.
Option B is the answer to your question..!!
Hope this helps you!!!!
Since the exponent (-3) is negative, flip the expression to: 1/(5n^4)^3.
Notice how the negative exponent becomes positive as you flip it.
Now evaluate the powers in the denominator: 1/((5^3)(n^4)^3
I separated the constant (5) from the variable (n) to show you how the powers are evaluated.
1/(5x5x5)(nxnxnxn)(nxnxnxn)(nxnxnxn)
—-> the power four means that there are 4 multiples of n in the parentheses. The power 3 corresponds to how many groups.
1/(125)(n^12)
= 1/125n^12
Answer:
<em>(D).</em>
Step-by-step explanation:
= A + 
(A). 12 + 16 > 20
(B). 10 + 18 < 30
(C). 4 + 5 < 12
<em>(D). 8 + 16 = 24</em>
