Answer

The inequality correctly represents the shaded region.

Steps

Step 1 :First, we need to understand the inequality. The inequality (2x+45)2+(2y0)225 represents a circle with center (22.5,0) and radius 5.

Step 2 :Let's choose a point not on the logo, for example, the origin (0,0). We will substitute this point into the inequality to see if it satisfies the inequality.

Step 3 :Substitute (0,0) into the inequality: (2(0)+45)2+(2(0)0)225

Step 4 :Simplify the expression: (45)2+(0)225

Step 5 :Calculate the result: 202525, which is false.

Step 6 :Since the point (0,0) does not satisfy the inequality, it is not in the shaded region.

Step 7 :Now, let's choose a point inside the logo, for example, (22,0). We will substitute this point into the inequality to see if it satisfies the inequality.

Step 8 :Substitute (22,0) into the inequality: (2(22)+45)2+(2(0)0)225

Step 9 :Simplify the expression: (1)2+(0)225

Step 10 :Calculate the result: 125, which is true.

Step 11 :Since the point (22,0) satisfies the inequality, it is in the shaded region.

Step 12 :The inequality correctly represents the shaded region.
