Awnser both part A and part B Part A is in picture

Part b: What mistake might the student have made

A: She found the sum of the square roots of the lengths of the legs

B: She found the difference of square roots of the lengths of the legs

C: She took the square root of the sum of the lengths of the legs

D: She took the square root of the difference of the lengths of the legs

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
