What polynomial has roots of −5, −4, and 1?
x3 − 8x2 − 11x + 20
x3 − x2 + 22x + 40
x3 + x2 − 22x − 40
x3 + 8x2 + 11x − 20

The last choice.

Step-by-step explanation:

The  last term is  - 20 and because we have a coefficient of 1 on the x^3,  and in order to get this last term  and the given roots the factors have to be

(x  + 5)(x + 4)(x - 1)  so it is the last option.

54

step-by-step explanation:

6x9

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
