2x^2 + 8x = 0
2x(× + 4) = 0
2x = 0
x = 0/2 =0
x + 4 = 0
x = -4
Answer:
15 miles
Step-by-step explanation:
1 day = 2.5 miles
6 days = ?
6 x 2.5 = 15

All together, he will go 15 miles.
i hope this helps and is right! p.s. i really need brainliest :)
Irrational, because if you simplify the root V72=6V2
1. x
2. x + 2
3. x + 4
x + 4 + 2x = 25. Second option is the answer.
Combine like terms
3x + 4 = 25
Subtract 4 from both sides
3x = 21
Divide both sides by 3
x = 7
