Bailey writes the expression g squared plus 14 g plus 40 to represent the area of a planned school garden in square feet. What factors can be used to find the dimensions of her garden?

To factor g² + 14g + 40, find two numbers that multiply to 40 and add to 14. Those numbers are 4 and 10, so g² + 14g + 40 = (g + 4)(g + 10). Therefore, the garden dimensions can be (g + 4) and (g + 10), as in choice A.
