Answer:

$x=12$

Step-by-step explanation:

we know that

A linear pair is two angles that are adjacent and form a line. The angle measure of a line is 180 degrees

In this problem we have that

$(10x-20)^o+(6x+8)^o=180^o$ --- by supplementary angles (form a linear pair)

solve for x

$(16x-12)=180$

$16x=180+12$

$16x=192$

$x=12$

On what interval(s) is the graph decreasing? - use interval notation

Anna [14]

The function is decreasing from -6 to -3, that is, on the interval (-6,-3), and again on the interval (1, infinity).

The function is increasing on (-3,1).

No local or absolute minimum.

(1,4) is an absolute max.

Find the product of 2x^4(4x^2 + 3x + 1).

lianna [129]

We want to find the product:

$\displaystyle{ 2x^4\cdot(4x^2 + 3x + 1)$ .

By the $\text{Distributive property}$ , we distribute $2x^4$ over each of the three terms inside the parenthesis:

$\displaystyle{ 2x^4\cdot(4x^2 + 3x + 1)=2x^4\cdot4x^2+2x^4\cdot3x+2x^4\cdot1$ .

Multiplying the coefficients, and adding the exponents we get:

$8x^6+6x^5+2x^4$ .

Answer: $8x^6+6x^5+2x^4$ .
