Hunter has a total of $9.60 in dimes and nickels. Let d be the number of dimes and n be the number of nickels. When the money values are in cents, the situation is modeled by the given equation.

How many dimes does Hunter have?

Hunter knows there are 12 more dimes than nickels. This fact is modeled by the given equation.

answer: can you give the

step-by-step explanation:

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
