Ответ:
A, C, D
Step-by-step explanation:
Solve all equations:
A.![33x-25=33x+25](/tpl/images/0322/3122/7298e.png)
This is incorrect equality, so the equation has no solutions.
B.![33x+25=33x+25](/tpl/images/0322/3122/bc371.png)
This is correct equality, so the equation has infinitely many solutions.
C.![33x-33=33x+25](/tpl/images/0322/3122/c0833.png)
This is incorrect equality, so the equation has no solutions.
D.![33x+33=33x+25](/tpl/images/0322/3122/6ae25.png)
This is incorrect equality, so the equation has no solutions.
Ответ:
We are adding like terms for this question. We combine same variables (ex. 5x+8x or 195xy+4xy) and all constants (without variables ex. 5+196).
So the side lengths are 5+x, 5+x, and xy.
We need to added them up for perimeter.
5+x+5+x+xy
Simplify
xy+2x+10
This would be the simplifies form.
