Point-slope form for a line:
We need a point (x₀,y₀) and the slope (m).
y-y₀=m(x-x₀=
We have the point (-7,2) and the slope (m=6); so:
y-2=6(x+7)
Answer: the equation in point-slope form would be: y-2=6(x+7)
The value of expression when n = 3 is 22
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to find the value of expression when n = 3
<em><u>Substitute n = 3 in given expression</u></em>

Thus the value of expression when n = 3 is 22
Answer:
The number of feet of fencing that he needs will be equal to the perimeter of the circular patio.
We know that the perimeter of a circle of radius R is equal to:
P = 2*pi*R
where pi = 3.14
Then if the radius of the patio is 70ft, the perimeter of the patio will be:
P = 2*3.14*70ft = 439.6 ft
Then he needs 439.6 ft of fencing to enclose the patio.
25m3
8-2=5
5X5=25
Therefore your answer is 25m2
