Anita hikes 7 miles due east and then 3 miles due north. rounded to the nearest mile, what is the shortest distance from the starting point to the ending point?
a. 4 b. 6 c. 8 d. 10 i think it's b. am i right?

The answer you are looking for is C. 8.

To find this you could Pythagorean Theorem. The base or bottom of the triangle would be 7, and the "leg" of the triangle would be 3. In this instance, we will call 3 "a" and 7 "b". We use these two numbers to find the missing value, which is "c" or the hypotenuse.

The formula for Pythagorean Theorem is "a^2 + b^2 = c^2". Then we follow these steps.

Here's a picture to show how I did this. I hope this helps!

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
