Given polynomials p(x), g(x), and r(x),
p(x) + (q(x) +r(x)) = (P(x) + g(x)) +r(x)
To verify the associative property of addition,
begin by finding the sum of the polynomials:
(3x + 4) + ((5x2 - 1) + (2x + 6))
x2 + x

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
