Answer:
C. 2mn and mn^2
Step-by-step explanation:
All of the other options are like terms.
Option A: -x+3x=2x
Option B: 4a+7a=11a
Option D. 3p^2q+(-p^2q)=2p^2q
Option C: These terms are not like terms since 2mn is not squared while mn^2 is squared.
Hence,
the correct option would be C.
Hope this helps!!! PLZ MARK BRAINLIEST!!!
Answer:
A; 4,6,8
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
First, subtract 25 from both sides of the equation:
5x + 25 (-25) = 35 (-25)
5x = 35 - 25
5x = 10
Isolate the variable, x. Divide 5 from both sides:
(5x)/5 = (10)/5
x = 10/5
x = 2
x = 2 is your answer.

Answer:
2x²-32 ⇒ x²=16⇒ (-4,4)
4x²-100 ⇒x²=25 ⇒(-5,5)
x²-55=9 ⇒x²=64 ⇒(-8,8)
x²-140=-19 ⇒x²=121 ⇒(-11,11)
2x²-18=0 ⇒x²=9 ⇒(-3,3)
Sorry if i am wrong but it's 40
