Well the 2nd one in the first row on the first page is 4.33. What you do first is figure out what you’re given and what your looking for. So you’re given the length of the hypotenuse which is 5, the 60 degree angle, and your trying to find the opp. And your trying to find the sin bc the sin is opp/hyp. So set it up like sin60 = x/5 and then you solve by doing 5 • sin60 in your calculator. This is so hard to explain so I would recommend looking up a vid about it online

Step-by-step explanation:
First to complete the square, it will need to look something like
a^2+2ab+b^2
so in order to get that we can see that 4n^2+8n seems to be missing a piece.
a is the square root of 4n^2 which is 2n.
8n/2n=4
4/2=2
b=2
so now add 2 to both sides of the equation so now it's
4n^2+8n+4=-13
rewrite as (2n+2)^2=-13
Now you see a negative number as the result of a exponent.
A number squared will never be negative.
Therefore the answer is
No Solutions

Hi there!
Let r be the number of matches that Rebecca's team won.
We know that Katheryn's team won 9 more matches than Rebecca's team, and we know that Katheryn's team won 52 matches.
Using this given information, we can create the following equation.

If you wish to solve this, we can subtract both sides by 9 to get the following value for r.

Have an awesome day! :)
