using data for population in the district of columbia, write an exponential model of the form a ∙ bx to estimate this population in the years after 2005.

a.) a ∙ bx = (550,521)(0.993)x

b.) a ∙ bx = (550,521)(0.990)x

c.) a ∙ bx = (550,521)(0.992)x

d.) a ∙ bx = (550,521)(0.991)x

Its C Hope dis helps!!!

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
