$\huge \bf༆ Answer ༄$

Let's solve this using unitary method ~

$\sf3 \: seconds = 63 \: meters$

$\sf1\: second= 63 \div 3 \: meters$

$\sf1\: second= 21 \: meters$

$\sf5\: seconds= 21 \times 5 \: meters$

$\sf5\: seconds= 105 \: meters$

Therefore , the ostrich will run 105 meters in 5 seconds.

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!!
