3x2 – 41x = -110
use quadratic formula

x=10 and x= 3.66667

Step-by-step explanation:

you would need to at 110 to both side to get c before you can solve the quadratic formula, once you have done that you should get 3x2-41x+110=0 than you can now put it in to the formula(-b) which will now be  than solve now combined to get the discriminant -4sc > 0 so there are two real roots which are,  simplify the radicals, x =  and x = that will turn into x = 10 and x= 3.66667

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)

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
