What is -8x-5x this is due in 5 mins so answer quick

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

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

it has to have an angle of 90 degrees
