Answer:
Your answer would be (x-4)
Step-by-step explanation:
If you follow the steps of factoring, first you need to set it up. I always start with the term with the variable first.
(x+_)(x+_)
And since we already know one of the factors, we can put that in our expression.
(x+6)(x+_)
Now remember the trick FOIL.
You multiply the FIRSTS together, then the OUTSIDES, then the INSIDES, and finally the LASTS.
To figure out our last blank we us this trick, but backwards. To get the 24 at the end of your expression x^2+2x-24 you multiply the LASTS together. So 6*_=-24. (remember the subtraction sign stays as a negative with the 24) That answer is -4
Hope that makes sense, and good luck!
Answer:
$5.32
Step-by-step explanation:
I think its $5.32 because there is at least 6 yogurts in the pack, and its not to expensive as the first one. Plus it has 2 more yogurts then the third one.
(i am so sorry if this dosent make sense)
After 4 weeks you have put 4 x 200 = 800 into the account, if the balance is 1700 you must have had 1700-800 = 900 in the account as an opening balance.
<span>Balance on the account = 900 + 200 x 4 = 1700 </span>
<span>For x weeks </span>
<span>y = 900 + 200 x </span>
<span>y-900 = 200 x </span>
<span>subtract 800 each side </span>
<span>y-900-800 = 200x - 800 </span>
<span>y-1700 = 200(x-4)</span>
