Answer:
35 × ![10^{4}](https://tex.z-dn.net/?f=10%5E%7B4%7D)
Step-by-step explanation:
7000= 7 × ![10^{3}](https://tex.z-dn.net/?f=10%5E%7B3%7D)
50= 5 × 10
So,
7000 × 50 =
35 × ![10^{4}](https://tex.z-dn.net/?f=10%5E%7B4%7D)
It would be 42 miles over 3 gallons
42/3=14
Hope this helps :)
Answer:
Step-by-step explanation:
hello :
here is two examples:
1) x²-9=0 means : x²-3² = (x-3)(x+3) = 0 .... use identity : a²-b² = (a-b(a+b)
use the Zero Product Property; x-3=0 or x+3=0 so : x=3 or x= +3
2) x²+4x = 0....using factoring : x(x+4)=0 means : x=0 or x+4=0
x=0 or x= - 4
