Jing and bob are each invited to a party. from previous experience, it is known that there is a 95% probability that at least one of them will actually go to the party. in addition, jing will actually go to the party with 80% probability, and bob will actually go to the party with 75% probability. based on this information, you are asked to determing what can be said about these two events.

yes

step-by-step explanation:

it would rotate about 180 degrees.

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
