Answer:
a trapezoid
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = x (sum of the lengths of the parallel sides) x height
Perimeter = sum of lengths of sides of a trapezoid
A = 1, d = 5 - 1 = 4
nth term = a + (n - 1)d = 1 + (n - 1)4 = 1 + 4n - 4 = 4n - 3
nth term = 4n - 3
Answer:
x ={-3, -4, -5 , -6, -7, ...}

Answer: y = -x - 16</h3>
========================================================
Explanation:
The given equation is the same as y = 1x+5 which is in y = mx+b form.
- m = slope = 1
- b = y intercept = 5
Anything perpendicular to this will have a slope of -1, which is the negative reciprocal of the original slope.
We'll use this perpendicular slope along with (x,y) = (-20,4) to find the equation of the perpendicular line.
y = mx+b
y = -1x+b ... plug in the perpendicular slope
4 = -1*(-20)+b ... plug in the x,y coordinates
4 = 20+b
4-20 = b
-16 = b
b = -16
Therefore, we go from y = mx+b to y = -x-16
