The four points A(-1,0),B(3,b),C(a,2) and D (-2,1) are the vertices of a parallelogram ABCD, find the value of a and b. I need for exam
​

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

is there a graph

step-by-step explanation:

if the rectangular pool has a area of 192 square ft. and length of 15 ft. you must divide 15 into 192. 192 ÷ 15 = about 13 ft.
