Write an equivalent expression for 13+9(x-3)

13+9x-27

or

-14+9x

Both work. They're both simplified versions of the one you put.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
