Let x be the number years since 1960, where the year 1960 is x = 0. An approximate equation of exponential regression of the form y = 954,724 . bx can be determined
to model the change in the population, y, after x number of years since 1960.
What is the approximate value of b in the regression equation?
A.0.99
B.0.91
C.0.86
D.0.13

$6.42

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)
