Answer:
9
Step-by-step explanation:
We know that the perimeter is 30.
2 x 6 is 12 and 30 - 12 is 18. We subtract 12 because we want to know the other sides
18 is the length of the remaining sides so we just divide by 2 and we get 9.
You factor the numerator and denominator and cancel the common factors. So maybe that should help you
2.34 * 10^5.
234000 = 2.34 * 10^5
- there are 5 digits after the first number so the exponent is 5.
