Answer 1

please show work...please HELP

Answer 2

Recall, a triangle of sides A, B, C, has perimeter=A+B+C

Answer 3

The sum of all sides is equal to 56. That's:
\[y+y+1+7=56\]
Can you solve this equation?

Answer 4

no

Answer 5

Fine.
\[y+y+1+7=56 \implies 2y+8=56\]
Subtract 8 from both side:
\[2y=48 \implies y=24\]
