Step-by-step explanation:
the two opposites Angles of this quadrilateral are equal, again the angles should sum up to 360
t-9+t-91+t-16+t+25=360
4t=360-101
4t=259
t=64.75
Answer:
y=x-2
Step-by-step explanation:
In the table, y is always 2 less than x. Therefore, the equation would be y=x-2. Hope this helps!
An equation whose roots are x=3 and x=11 is
|(x-3)(x-11)|=0
We can check that, plugging in x=3 or x=11, makes both sides of the equation equal.

Answer: Choice B</h3>
===================================================
Explanation:
The idea is that for any term, we add on the common difference d to get the next term. For example, the sequence {3, 7, 11, 15, 19, 23, ...} has us add on 4 each time so d = 4 in this case.
3+4 = 7
7+4 = 11
11+4 = 15
and so on. The nth term is represented by the notation while the term just before the nth term is written as
So adding d onto the term just before the nth term gets us the nth term which is how we end up with
This is the recursive form of the arithmetic sequence. The closed form is written as
