Find the coordinates of point f.

a. (0, 2)
b. (–2, 0)
c. (2, 0)
d. (0, –2)

i dony know

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3

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

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
