The answer is D. Adding the negative threes would equal to negative six. Multiplying them would equal to positive nine. Therefore, D is the correct answers.

The given trinomial can be factored using the factorization method.

x² -6x +9
= x² -3x -3x +9
= x(x-3) - 3(x-3)
= (x-3)(x-3)

Thus, (x-3)(x-3) is the factored form of the polynomial.

So the correct answer is option D

Answer:

125%

Step-by-step explanation:

Is means equals and of means multiply

40 = P * 32 where P is in decimal form

Divide each side by 32

40/32 = P

1.25 = P

Now change to percent form ( multiply by 100)

125%

Answer:

A. 24.5

B. 29.6

Step-by-step explanation:

A.

19 - 13.5 = 5.5

30 - 5.5 = 24.5

24.5 - 5.5 = 19

24.5

B.

43.8 - 36.7 = 7.1

36.7 - 7.1 = 29.6

29.6 - 7.1 = 22.5

29.6

Solve the given differential equation by using an appropriate substitution. The DE is a Bernoulli equation.

Mama L [17]

Multiplying both sides by $y^2$ gives

$xy^2\dfrac{\mathrm dy}{\mathrm dx}+y^3=1$

so that substituting $v=y^3$ and hence $\frac{\mathrm dv}{\mathrm dv}=3y^2\frac{\mathrm dy}{\mathrm dx}$ gives the linear ODE,

$\dfrac x3\dfrac{\mathrm dv}{\mathrm dx}+v=1$

Now multiply both sides by $3x^2$ to get

$x^3\dfrac{\mathrm dv}{\mathrm dx}+3x^2v=3x^2$

so that the left side condenses into the derivative of a product.

$\dfrac{\mathrm d}{\mathrm dx}[x^3v]=3x^2$

Integrate both sides, then solve for $v$ , then for $y$ :

$x^3v=\displaystyle\int3x^2\,\mathrm dx$

$x^3v=x^3+C$

$v=1+\dfrac C{x^3}$

$y^3=1+\dfrac C{x^3}$

$\boxed{y=\sqrt[3]{1+\dfrac C{x^3}}}$
