PLEASEEE help with these multiple choice answers, will mark brainliest !!

B. −x^2+2x+4

Step-by-step explanation:

(f-g)(x)

fx - g=

6x^2+4x−7−2x−7x^2+11

=6x^2+4x+−7+−2x+−7x^2+11

Combine Like Terms:

=6x^2+4x+−7+−2x+−7x^2+11

=(6x^2+−7x^2)+(4x+−2x)+(−7+11)

=−x^2+2x+4

1. minimum

2. 6400

3. eight

hope this !

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
