I can help! With the Greatest Common Factor you figure out the greatest number that can go into all numbers. The number here would be the 2. You then divide 2 by all the numbers in the problem.
You would end up getting x^2 + 6x + 9
I use to struggle with this too. Hope this helps! Have a great day!!
it's should be 220 because your starting point is at 70 then add 15 for 10 weeks which means you have to add 15*10 or 150 to 70 which will give you 220
Hey! The most intuitive way I've been explained the idea of subtracting negative numbers is in terms of debts. <em>Subtracting</em> a debt from your bank account has the effect of <em>adding </em>money to it. Imagine you had $10 in your account, but you owed $8 in debt; your current balance would show $2 in your account. If you <em>took away that debt</em>, though, you'd be back up to $10. If we imagine your funds as positive numbers and your debts as negative numbers, we could express taking away that debt as:
2 - (-8) = 10
Hope that makes a little more sense!
