8m^2+18m+9=0
Multiply 2m by 4m to get 8m^2. Multiply 2m by 3 to get 6m. Multiply 3 by 4m to get 12m. Add the 6m and 12m to make 18m. Multiply 3 by 3 to get the integer 9. Set it all equal to 0.
The answer is B
the steps are these
interchange the x and y variables
x=5y-8
solve for y so we get
y = x+8

I believe it’s 2 because rise/run and 14/7 = 2
13.45 x $4.30= $57.835 ≈ $57.84
13.45 x 40.2=540.69 miles
