Arectangle has vertices at a(4,1), b(1,1), c(1,-6), and d(4,-6). what is the area of the rectangle?

using the given coordinates, the rectangle is 7 by 3 units

area = 7*3 = 21 square units

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
