Answer:
4725
Step-by-step explanation:
25-10=15
15^2=225
10*45*10=4500
225+4500=4725
It can be found by using the formula,
an = a+(n-1)d
The answer is 7/4 I added my work there sorry if it’s kinda messy
Answer:

Step-by-step explanation:
Given:
The equation of the known line is:

A point on the unknown line is (-4, 4)
Now, since the two lines are parallel, their slopes must be equal.
Now, slope of the known line is the coefficient of 'x' which is
.
Therefore, the slope of the unknown line is also 
Now, for a line with slope 'm' and a point on it
is given as:

Here,
. Therefore,

Hence, the equation of the unknown line is
.
No. Área of a circle is determined by this formula A=πr^2. Answer is 153.94
