To get home from school, bob walks four blocks north and three blocks east. what is the straight line distance between bob’s house and his school?

The way to solve this is by drawing a picture to get a visual on this problem. after that, you'll see that the 4 blocks north, the 3 blocks east, and the straight line across form a triangle. you can use the pythagorean theorem to find the third side.
a² + b² = c²  ... use the two numbers given

(4)² + (3)² = c²
16 + 9 = c²
25 = c²
c = 5

the distance of the straight line between bob's house and his school is 5 blocks.
