The answer is C because multiply and divide by (x+2)(2x+3)
= ( (x+9)(x+2) + (x+4)(2x+3) ) ( (x+2)(2x+3))
= ( (x^2+11x+18) + (2x^2+11x+12) ) / ( 2x^2+7x+6)
= (3x^2+22x+30) / (2x^2+7x+6)
Answer:
Step-by-step explanation:
(x² + 6x + 9)(x)= x²*x + 6x*x + 9*x = x³ + 6x² + 9x

Step-by-step explanation:
<u>Linearization</u>
It consists of finding an approximately linear function that behaves as close as possible to the original function near a specific point.
Let y=f(x) a real function and (a,f(a)) the point near which we want to find a linear approximation of f. If f'(x) exists in x=a, then the equation for the linearization of f is

Let's find the linearization for the function

at (0,5) and (75,10)
Computing f'(x)

At x=0:

We find f(0)

Thus the linearization is


Now at x=75:

We find f(75)

Thus the linearization is

Answer:
5120 cm^2
Step-by-step explanation:
Base area = (18 x 40)/2 = 360 cm^2
Base perimeter = 18 + 41 + 41 = 100 cm
LA = 100 x 44 = 4400 cm^2
surface area = 360 x 2 + 4400 = 5120 cm^2
