Plzz could someone me out with this and explain

It would be D because X^2 is different from 3x you would just multiply X^2 by 1 and 3x by 1 to get x^2+3x

3x³+3x so C

Step-by-step explanation:

Multiply both the given equations

x²(3x) = 3x³

+1(3x)=+3x

Then combine

3x³+3x so C

is there a picture

step-by-step explanation:

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
