Which statement is true of a rectangle that has an area of 4x2 + 39x – 10 square units and a width of (x + 10) units?

Divide the area by the width to find the length: (4x² + 39x − 10) ÷ (x + 10) = 4x − 1. The perimeter is twice the sum of the length and width: 2[(4x − 1) + (x + 10)] = 10x + 18. Therefore, the true statement is that the rectangle has a perimeter of (10x + 18) units.
