The family needs 4 days to cover 1,400 miles
<span> Given polynomial x^2+8x-48 = 0</span>
<span>x^2+12x-4x-48 = 0</span>
<span>x(x+12)-4(x+12) = 0</span>
<span>(x+12)(x-4) = 0</span>
<span>x+12 = 0</span>
Subtract 12 from each side.
<span>x+12-12 = 0-12</span>
<span>x = -12</span>
<span>and x-4 = 0</span>
Add 4 to each side.
<span>x-4+4 = 0+4</span>
<span>x = 4</span>
<span>Roots are -12,4.</span>

Answer:
Dori:3x+3y=11.25
Nemo:4x+2y=10
Step-by-step explanation:
Let x and y represent tacos and double Deckers respectively.
For three tacos and three double Deckers, Dori pays $11.25
Writing an equation the statement, we obtain
3x+3y=11.25
Also,for four tacos and two double Deckers, Nemo pays $10
This implies
4x+2y=10
