R(s+t)=st; solve for s

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

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

r and t.

both are 64 degrees.
