Question

Im trying to see if what i think the answer is is correct for the width i got 2x^2+1

Answer 1

Given the expression:

`10x^2+5x`

we already know that 5x is a common factor, then, if we divide each term by 5x we get:

`\begin{gathered} (10x^2)/(5x)=2x \\ (5x)/(5x)=1 \end{gathered}`

then, we can factor the expression like this:

`10x^2+5x=5x(2x+1)`

therefore, the width of Heng's area model is 2x+1
