A house contains one 12-foot-×-14-foot bedroom, one 12-foot-×-10-foot bedroom, and one 8-foot-×-12-foot bedroom. What’s the total amount of carpeting needed to carpet all three bedrooms?
To carpet all of them you need to get the area from all three and add. (12 x 14) + (12 x 10) + (8 x 12) = ?
so multiply the numbers then add?
Yes. Multiply first always...Unless addition is in parenthesis. --> ( ) these
i got 384
Correct
ok here's an other problem that i would like to understand how to solve. In a manufacturing plant that produces new computers, a 0.15 probability exists that a computer will be defective. If five computers are manufactured, what’s the probability that all of them will be defective?
I don't know that one :/
its ok thank you
