Which equation can be used to find the unknown length, b, in this triangle? 5 in
4 in
A) 4^2+b^2= 5^2
B) 4^2-b^2=5^2
C) 5² +b^2=4²
D) 5^2+b^2=4^2

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
