Frank thinks that 2x + 3x^2 is the same as 5x^3. which statement shows that it is not the same?
a. 2x+3^2=5x^2
b. 2(6)x3(6)^2not equal to 5(6)^3
c. 2x +3x not equal to 5x
d. 2(4) +3(4)^2 not equal to 5 (4)^3

I believe the answer is D. If you work it out, 
2(4) + 3(4)^2 doesn't equal 5(4)^3 because 
8 + 3*(16) 5 * (64)
8 + 48 320
56 doesn't equal 320. 

A doesn't disprove anything, B changes the original equation from adding to multiplying, and C is incorrect, 2x + 3x does equal 5x.

D is the correct answer. 

I got this right, I hope it helps

Step-by-step explanation:

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
