Answer:
2a or 2b
Step-by-step explanation:
//No options to pick, but here it is:
a - b = 0 //Add b on both sides.
a = b
If a is equal to b then a = b can be written as a = a or b = b, if that true than:
a + b can be also written as:
a + a which makes its 2a or
b + b which is equal to 2b.
//Hope it helps.
Answer:
a-b=0→ a=b
b=a
therefore it ends up being↓↓↓
a.b→→ substituting→→ a*(a)=a² or bxb=b²
hope this helps :)
