Estimate the quotients 5.1 308.3 divide 5 = ? 467.6 divide 8 = ? 737.5 divide 9 = ? 645.6 divide 7 = ? that all questions that i have problems with me.

y + 11 = (1/4)(x + 16)

step-by-step explanation:

i honestly dont know

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

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
