Answer:

(x-8) is the factor.

Step-by-step explanation:

The given trinomial is x^{2}-6x-16.

We need to find the factor of this trinomial.

x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)

The factors of x^{2}-6x-16 is (x-2) and (x-8).

So, the factor of x^{2}-6x-16 is (x-8). Hence, the correct option is (B).

Choose two angles that are each separately alternate exterior angles with 412.
Alborosie

Answer:

∠2 and ∠5

Step-by-step explanation:

we know that

<u>Alternate Exterior Angles</u> are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

In this problem

∠12 and ∠2 are alternate exterior angles

∠12 and ∠5 are alternate exterior angles

therefore

∠2 and ∠5 are each separately alternate exterior angles with ∠12

3. What value of makes a true equivalent fraction statement.<br> 5 30<br> 54<br> C
VashaNatasha [74]

Answer:

x = 9

Step-by-step explanation:

We need to find x which will make an equivalent fraction statement.

\frac{5}{x} = \frac{30}{54}

5 x 6 = 30

x x 6 = 54 (to find x we should do 54 ÷ 6 which = 9)

So:

\frac{5}{6} = \frac{30}{54}

x = 9

hope this helps :)

What is the numerical coefficient of the a^8*b^2 term in the expansion of ((1/3)a^2 - 3b)^6 ?
zhuklara [117]

In the binomial development, the main problem is calculation of binomial coefficients.

If we want to get term a∧8*b∧2 we see that this is the third member in binomial development (n 2) a∧n-2*b∧2

The given binomial  is ((1/3)a∧2 - 3b)∧6, the first element is (1/3)a∧2, the second element is (-3b) and n=6 when we replace this in the formula we get

(6 2) * ((1/3)a∧2)∧(6-2) * (-3b)2 = (6*5)/2 * ((1/3)a∧2)∧4 *9b∧2= 15*(1/81)*9 *(a∧8b∧2) =

= 15*9* a∧8b∧2 = 135*a∧8b∧2

We finally get numerical coefficient 135

Good luck!!!
