D. Rx) = x2 - 4x + 10

Step-by-step explanation:

R(x)=(x-2)^2+6

R(x)=(x-2)^2+6

=(x-2)(x-2)+6

=x^2-2x-2x+4+6

=x^2-4x+10

R(x) = x^2 - 4x + 10

\frac{3x^3+9x^2-6x}{-3x}
Since the denominator is a monomial, we divide each term of the trinomial in the numerator by the denominator.
\frac{3x^3}{-3x} = -1x^2, because 3/-3 = 1 and x³/x = x².
\frac{9x^2}{-3x}=-3x; 9/-3 = -3 and x²/x = x.
\frac{-6x}{-3x} = 2; -6/-3 = 2 and x/x = 1, so we have 2*1  = 2.
Together this gives us -x^2-3x+2

Simplify. <br><br> −3x3(−2x2+4x−3)
stepladder [879]

Answer:

-3x^3(-2x^2+4x-3) simplifies to 6x^5-12x^4+9x^3

Step-by-step explanation:

Given expression -3x^3(-2x^2+4x-3)

We have to simplify the above expression,

Consider the given expression -3x^3(-2x^2+4x-3)

Multiply each term in brackets by -3x^3, we get,

-3x^3(-2x^2+4x-3)=-3x^3(-2x^2)-3x^3(4x)[-3x^3(-3)

Solving further,  using x^n\cdot x^m=x^{n+m} we get,

-3x^3(-2x^2)-3x^3(4x)[-3x^3(-3)=6x^5-12x^4+9x^3

Thus, -3x^3(-2x^2+4x-3) simplifies to 6x^5-12x^4+9x^3

Are my angles correct?
Licemer1 [7]

Answer:

Yes. You are correct.

Step-by-step explanation:

Tan(U) = opposite / adjactent

Tan(U) = 7*√3 / 7

Tan(U) = √3

Just off the top of my head, they look right.

U = Tan-1 (√3)

U = 60

Therefore tan(W) = 90 - 60 = 30
