Plz help me to see the question zoom in my test is almost out 15 points

C. Triangle 1 and Triangle 3

Step-by-step explanation:

For a pair of triangles to be similar, they would either need to have all equal angles or have corresponding sides in the same ratio.

The triangles below only display sides so we must look for the pair of triangles with corresponding sides in the same ratio.

We can conclude that triangle 1 and triangle 3 follow this rule since they have sides with the ratio 2:1.

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
