Answer 2

Answer:

The Atlantic Ocean and Pacific Ocean covers about $9.6*10^7\ mi^2$

Step-by-step explanation:

Let

x -----> area covered by the Atlantic Ocean

y -----> area covered by the Pacific Ocean

we know that

The area that covers the Atlantic Ocean and Pacific Ocean is equal to the sum of  the area covered by the Atlantic Ocean and the area covered by the Pacific Ocean

so

$x+y$

we have

$x=3.2*10^7\ mi^2$

$y=6.4*10^7\ mi^2$

substitute

$x+y=3.2*10^7\ mi^2+ 6.4*10^7\ mi^2=9.6*10^7\ mi^2$
