Answer: 3
Step-by-step explanation: To find the sum of these two numbers, remember that adding a negative is exactly the same thing as subtracting a positive. In other words, when we see 18 + (-15), we can change the problem so it's easier to understand and we will change in to 18 - 15.
Now, this is just basic subtraction.
18 - 15 = 3
Therefore, 18 + (-15) = 3
The correct answer to the question that is being asked and presented above would be 'composite'. If there are two or more basic geometric figures combined, they form what is called a 'composite' figure.
okay realize that the distance traveled by the small plane, distance traveled by jet, and the distance between them makes a right triangle. Using Pythagorean theorem and allowing x be the distance between them, x² = (20 miles)² + (64.5 miles
x = 67.53 miles the distance between the two entities in nearest tenth is approximately 67.5 miles.
