Ответ:
"If the "break apart stradegy" is the same as what I was taught, you would add the ones place, the tens place, the hundreds place, and so on. This would be 7 + 8 then 40 + 50 and then 200 + 300. Add what you got together. So 247 + 358. You would get 605."

x^2=7^2+24^2
x^2=49+576
x^2=625
x=sqrt(625)=25
