Please help me the question is on the file ;-;
12345 [234]

Answer:

D) 3x + 15 ≥ 300

Step-by-step explanation:

The rectangle must have a area of AT LEAST 300 square ft, or 300 or greater. Use the greater than or equal sign: ≥ 300.

Note that your are solving for the area, and that this shape is a rectangle. To get the area of the rectangle, simply multiply length and width:

(3) * (x + 5) = Area of rectangle.

Distribute the 3 to all terms:

3(x + 5) = 3x + 15 = Area of rectangle.

Put the two parts together:

3x + 15 ≥ 300.
