The graph shows the location of Amber's, Betsey's, and Claire's houses. Each unit on the graph represents 1 block.
A coordinate plane graph is shown. Ambers house is located at negative 3 comma negative 3. Betseys house is located at 5 comma negative 3. Claires house is located at 5 comma 4.
If Amber walks from her house to Claire's house, then on to Betsey's house along the path shown, how far will she have walked in blocks? Round your answer to the nearest hundredth. (4 points)
15.32 blocks
17.63 blocks
18.63 blocks

Cade and Tyce both tried to find the missing side of the right triangle.
A right triangle is shown. The legs are labeled 6 and 9. A right angle is labeled in between them.
Cade's Work Tyce's Work
a2 + b2 = c2 a2 + b2 = c2
62 + b2 = 92 62 + 92 = c2
36 + b2 = 81 36 + 81 = c2
b2 = 45 117 = c2
Square root b squared equals square root 45. Square root 117 equals c squared.
b ≈ 6.71 10.82 ≈ c
Is either of them correct? Explain your reasoning. (5 points)
