You haven't posted the answer choices, but I think I've run across this question before and remember the answer. The answer should be whichever letter says as follows: "Smoking damages cilia in the trachea and more particles enter the lungs. Hope this helps!~
The area of the shaded part is 52 sq. inches. The correct option is b. 52 sq. inches
<h3>Calculating Area</h3>
From the question, we are to determine the area of the shaded part
In the given diagram, the shaded part is a rectangle
Area of a rectangle = Length × Width
Length of the shaded part = 18 inches - 4 inches - 1 inch = 13 inches
Width of the shaded part = 6 inches - 2inches = 4 inches
Then,
Area of the shaded part = 13 inches × 4 inches
Area of the shaded part = 52 sq. inches
Hence, the area of the shaded part is 52 sq. inches. The correct option is b. 52 sq. inches

Answer: The equation of a straight line is:
y = mx + b
m is the slope, and that is -2.
Hope this helps:/
The first answer is correct as the dot is on -34.5 and the bar is shaded to its left, therefore, x is less than -34.5
Hope this helped :)
The y intercept (when x=0) is 40
the slope is 15 ( slope= rise/run= 15/1=15)
therefore, the equation of the line is y=15x+40
