Subtract the length from the perimeter because length + width = perimeter so 46ft - 11ft = 55ft
That you will have to used it everyday in life.

Actually Welcome to the concept of straight lines.
==> y-y1 = m(x-x1)
==> y = mx+c
these two are the straight line equation, so we get as,
=> 0-0 = m(8-(-7)
==> 0 = m(15)
==> hence, 15m = 0
Answer:
Name: Circle A
Chords: Chord DP, Chord HC
Tangent: EFG
Step-by-step explanation:
Name a circle by the center, in this case it's A.
Chord: A chord is a line only in the circle, not outside of it, and its endpoints are right on the circle.
Tangent of a circle: "Tangent" means touching, and this is a line, in terms of a circle, that touches the circle but is not INSIDE of the circle.
