Over the past several years, there has been a dramatic increase in obesity rates in the United States. The CDC website noted that approximately 16 out of 100 adults in the United States were obese in 1995.
What was the percentage of adults who were obese in 1995?
O 0.016% of American adults were obese in 1995.
O 6.25% of American adults were obese in 1995.
16% of American adults were obese in 1995,
o 1.6% of American adults were obese in 1995.
0.16% of American adults were obese in 1995.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

idk what the heck he answer is, i’m just putting this here so i finish my account

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
