Answer:
What's the question??
Step-by-step explanation:
If those are your roots, in factorization form they are [x-(-1+i)][x-(-1-i)], which simplifies to (x+1-i)(x+1+i). FOIL that out like you would anything else to get the mess that looks like this:
. Putting things in order makes it easier to deal with.
. Canceling out what we can, gives us
.
. That simplifies to
, which of course gives us
and
is the final result. Your missing term there is 2x
Assuming you meant her sister used 200 minutes which im still a little unclear of
if everyone in the family used 350 minutes it would add up to 1400, this is the number you want your minutes to add up to
400
350
200 thats 950
subtract 950 from 1400 and you have 450
450 Minutes is your answer

Answer:
7 days
Step-by-step explanation:
So! Ms. Masi earns $11.25 everyday, and is paying her brother back everyday. Let's make an equation to solve for the number of days!
11.25d = 72 <em>(d = # of days)</em>
<em>Now, we have to solve this equation to see how many days (d) it will take Ms. Masi to pay her brother back.</em>
<em></em>
11.25d = 72
÷11.25 ÷11.25 (Divide by "11.25" to get the variable by itself)
d = 6.4
<em>Since, she only gets 1 pay per day, Ms. Masi will have to wait til her 7th day to pay her brother back.</em>
