Perform the indicated operation. PLEASEE HELPP HURRYY!! (3 + i) + (5 + 7i) = A) -2 + 6i B) 2 + i C) 8 + 6i D) 8 + 8i
Dovator [93]

Answer:

\boxed{ \bold{  \huge{ \boxed{ \sf{8 + 8i}}}}}

Option D is the correct option.

Step-by-step explanation:

\sf{(3 + i) + (5 + 7i)}

When there is a ( + ) in front of an expression in parentheses , there is no need to change the sign.

That means, the expression remains the same.

Just remove the unnecessary parentheses

⇒\sf{3 + i + 5 + 7i}

Collect like terms and simplify

⇒\sf{3 + 5 + i + 7i}

⇒\sf{8 + 8i}

Hope I helped!

Best regards!!
