The sides of ∆abc are 30 units, 40 units, and 60 units long. the corresponding sides of ∆xyz are r times as long as the sides of ∆abc. the expression that gives the perimeter of ∆xyz is . if the area of ∆abc is n square units, the area of ∆xyz is square units.

can you make your screen more see able?

then i might be able to .

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
