Answer:2nd one starting from top left
Step-by-step explanation:
there r two sides congruent and an angle in between
Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest
5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false
$3, $1, $5, $2, $3, $9, $1 = $24 - $1 = $23 - $1 = $22.
