Step-by-step explanation:
20a + 158+6c=you will expand the brackets
= so it is 120+60+48
20a+158+6c=120+60+48
20a+ 6c=120+60+48-158
20a+6c=70
20a divide by 20+6c divide by 6 on both side
a + c = 0.58

Let s be the side of square cardboard
We know that perimeter of square =f(s=)
Then, perimeter of cardboard=

Dividing by 4 on both sides

Hence, the domain of function
Therefore, option d is true.
