Madison says her pet cat weighs about 8 ounces. Her brother Phillip says the cat weighs about 8 pounds. Whose estimate is more accurate? Use benchmarks to explain your answer.

8 Pounds

Step-by-step explanation:

A cat that weighs 8 oz would be half of a pound, and that seems highly inaccurate. Most cats on average in the U.S. weigh 8 pounds, therefore that is your answer.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
