y(2x + 3y)(2x + 3y)
Multiply (2x + 3y) * (2x + 3y)
y(2x * (2x + 3y) + 3y * (2x + 3y))
y((2x * 2x + 3y * 2x) + 3y * (2x + 3y))
Reorder the terms:
y((6xy + 4x2) + 3y * (2x + 3y))
y((6xy + 4x2) + 3y * (2x + 3y))
y(6xy + 4x2 + (2x * 3y + 3y * 3y))
y(6xy + 4x2 + (6xy + 9y2))
Reorder the terms:
y(6xy + 6xy + 4x2 + 9y2)
Combine like terms: 6xy + 6xy = 12xy
y(12xy + 4x2 + 9y2)
(12xy * y + 4x2 * y + 9y2 * y)
(12xy2 + 4x2y + 9y3)</span>
151 because the a and the b are that number so the other number would need to add up so the answer is 151
Answer : 21
Hope this Helps :)
Because at any angle it is still a triangle and looks the same
Answer: f(x) = 38000(0.97)^x
Step-by-step explanation:
We would apply the formula for depreciation which is expressed as
A = P(1 - r)^ t
Where
A represents the value of the car after t years.
t represents the number of years.
P represents the initial value of the car.
r represents the rate at which the car is depreciating
From the information given,
P = 38000
r = 3% = 3/100 = 0.03
t = x years
Therefore, the function f(x) that's models the value of the car x years after it's purchase would be
f(x) = 38000(1 - 0.03)^x
f(x) = 38000(0.97)^x
