Answer:

see explanation

Step-by-step explanation:

the centroid is where the medians intersect.

On each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint.

(3)

GF = $\frac{1}{2}$ CG = $\frac{1}{2}$ × 14 = 7

CF = CG + GF = 14 + 7 = 21

(4)

GD = $\frac{1}{3}$ AD = $\frac{1}{3}$ × 45 = 15

AG = 2 × GD = 2 × 15 = 30

(5)

GE = 2 × BG , that is

9x = 2(3x + 6) = 6x + 12 ( subtract 6x from both sides )

3x = 12 ( divide both sides by 3 )

x = 4

Determine if x-6 is a zero and find the quotiant and the remainder

sergiy2304 [10]

Answer:

○ A. No, x = -6 is not a zero of the polynomial.

The quotient is x - 29, and the remainder is 234.

Step-by-step explanation:

[x - 3][x - 20] >> Factored Form

Obviously, this is not a zero. Now, to get the remainder, we have to plug in the vertical line of x = -6 into its conjugate, meaning an expression with opposite signs, which is x + 6. This is the expression we divide the dividend by, so you will have this:

\frac{{x}^{2} - 23x - 60}{x + 6}

Since the divisor is in the form of x - c, using Synthetic Division, we get this:

x - 29 + \frac{234}{x + 6}

You see? You have x - 29 in the quotient, and you have 234 as the numerator remainder.
