Answer:
Step-by-step explanation:
1 2(x-4)-3(x-2)
=2x-4x-3x+6
=2x-7x+6
2 a²+a
=a(a+1)
Total cost = $15,867 + $(15,867 x 0.0525) = $15,867.00 + $833.02 = $16,700.02
10% of the total cost = 0.1 x $16,700.02 = $1,670.00
Principal balance = $16,700.02 - $1,670.00 = $15,030.02

Answer:
d = 49
Step-by-step explanation:
Given that the expression is a perfect square of the form
(ay - b)² = a²y² - 2aby + b²
Then comparing like terms
a²y² = 25y², that is
a² = 25 ⇒ a = 5
and -2aby = - 70y, thus
2ab = 70, that is
2(5)b = 70
10b = 70 ⇒ b = 7
b² = 7² = 49
Hence
25y² - 70y + d = (5y - 7)² = 25y² - 70y + 49
Thus d = 49
