The answer is A.

A is correct because...

(7z+23)-(15z+9)       There's an invisible positive 1 in front of (7z+23). Distribute.

7z+23-(15z+9)         Distribute the negative sign among 15z and 9.

7z+23-15z-9            Now, combine the like terms, 7z, and -15z. 7z - 15z

-8z+23-9                 Combine the like terms, 23 and -9. 23 - 9

-8z +14

The area of the arrow given in the figure is 610 square cm

<h3>Area of composite figure</h3>

The given figure is made up of rectangle and triangle. The area is expressed as:

Area = Area of rectangle + area of triangle

Area of the arrow = (15*20) + 0.5(31 * 20)

Area of the arrow = 300 + 310
Area of the arrow = 610 square cm

Hence the area of the arrow given in the figure is 610 square cm
