12x^2 -13x - 7175 = 0.

Step-by-step explanation:

what I did was (4x+5)(3x-7) = 7140

Then I expanded it (so 12x^2 +15x - 35 -28x = 7140)

I then took away 7140 from both sides to have a quadratic equation to solve

853.3

step-by-step explanation:

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)
