which of the following represents the factorization of the binomial below?
x^2-81
a (x-9)(x-9)
b (x)(x-81)
c (x+9)(x+9)
d (x+9)(x-9)

D

Step-by-step explanation:

x² - 81 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = x and b = 9, thus

x² - 81 = (x + 9)(x - 9) → D

care to share were the trapezoid shown is ?

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
