Rectangle abcd has vertices a(-3, 1), b(5, 7), c(9, 4), and d(1, -2). calculate the area of rectangle abcd.

It's not a rectangle. Look at the picture.

It is a parallelogram.

The area of the red rectangle:

The areas of the right triangles:

The area of a parallelogram:

the answer is 489

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
