1. (b+2)(b+2)=b^2 +4b + 4 (FOIL)
2. FOIL; x^2 + 6x + 9
3. correct

Answer:
7.4825 km or 7.48 km (rounded to nearest hundredth)
Step-by-step explanation:
<u>Ranch's measurements rounded up to the nearest hundredth:</u>
1st measurement =
= 7.75 km
2nd measurement =
= 7.25 km
3rd measurement = 7.3(recurring) = 7.33 km
4th measurement = 7
