Are these triangles congruent if so what what theorem can be used? 1. SSS
2. SAS
3. ASA
4. AAS
5.HL
6. NOT CONGRUENT

it should be SSS but if not that then not congruent

Step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
