You need a 20% increase on the sale of toilet paper over last month to reach your sales goals for the quarter. Toilet paper sales for last month totaled 8,000 units. How many additional toilet paper units do you need to sell this month to achieve your sales goal?

(x+3)(x+7)

step-by-step explanation:

answer: i ! the answer is   9000 seconds, also d

hope i

-lavira : )

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
