Answer
Find out the perimeter of the isosceles triangle.
To prove
As shown in the figure.
P(0,4) , Q(-2,0) and R(2,0) are the vertices of the triangle PQR.
Formula

As P(0,4) and Q(-2,0)


In the isoceles triangle the two sides of the triangles are equal .
Therefore PQ = PR

As Q(-2,0) and R(2,0)


QR = 16 unit


I just learned this, I believe that the answer is <span>a1=21;an=7⋅an−1</span>
Answer:36
Step-by-step explanation:
I actually just answered this problem on a website the answer is 36.
Answer:
The equation of the line would be y = -2x + 7
Step-by-step explanation:
In order to solve this, use the point and the slope in point-slope form. Then solve for y.
y - y1 = m(x - x1)
y - 5 = -2(x - 1)
y - 5 = -2x + 2
y = -2x + 7
