Full question:

Heng was trying to factor 10x²+5x. She found that the greatest common factor of these terms was 5x and made an area model: What is the width of Heng's area model?

The width of the area model is 2x + 1

Step-by-step explanation:

Given

Expression: 10x² + 5x

Factor: 5x

Required

Width of the Area Model

To solve this, I'll assume the area model is Length * Width

Provided that we're to solve for the width of the model.

This implies that; Length = 5x

Area = Length * Width

And

Area = 10x² + 5x

Equate these two

Length * Width = 10x² + 5x

Factorize express on the right hand side

Length * Width = 5x(2x + 1)

Substitute 5x for Length

5x * Width = 5x(2x + 1)

Divide both sides by 5x

Width = 2x + 1

Hence, the width of the area model is 2x + 1
