a) O
b) 1
d)-1
c)2​

Answer 1

Step-by-step explanation:

If a = -1, then a' +a? +a+1= 2

Answer 2

$\mathbb{QUESTION}$

If a = -1, then a+1=?

$\huge{\mathcal {\purple {A}\green {n}\pink {s}\blue {w}\purple{e}\green {r}}}$

a=-1 then we have to find a+1

then substitute a value in a+1

So, after substitution -1+1 =a+1

So, -1 and +1 get cancelled because they are in negative signs

So, answer is 0

$\mathbb{CHECK}$

a+1=+1-1

a+1=0

a=-1

$\mathbb{MORE \: INFORMATION}$

+1-1=0

1/0= cannot be determined

0/1=0
