⅔ and 8/12 form a proportion.
Step-by-step explanation:
what i understand is x is a axis
Im not to sure but I am pretty sure it's 1/10
To start, first distribute the x's to their expressions. This would look like this:
(x*x+2*x)+(x*x+x*3)=x^2+2x+x^2+3x
Then, you combine like terms or simplify, and you get an answer of 2x^2+5x
