What else would need to be congruent to show that abc=def by sas

C

Step-by-step explanation:

To show congruency using the SAS postulate

We require 2 sides and the included angle ( the angle between the 2 sides ) to be congruent.

Thus AC ≅ DF → C

Gives 2 sides and the angle between them.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
