12. = s

13. A = wh

14. P = a + b + c

15. A =

16. P - c - b = a

Step-by-step explanation:

12. P = 5s

Divide both sides by 5:

P/5 = 5s/5

= s

13. = w

Multiply both sides by h:

(h)= w(h)

A = wh

14. P - c = a + b

Add c to both sides:

P - c + c = a + b + c

P = a + b + c

15. 2A = bh

Divide both sides by 2:

2A/2 = bh/2

A =

16. P = a + b + c

Subtract c from both sides of the equation:

P - c = a + b + c - c

P - c = a + b

Subtract b from both sides:

P - c - b = a + b - b

P - c - b = a

Hope this helps :)
