Answer:

D)\:(3x^{2} +2)(x+4)

Step-by-step explanation:

3x^{3}  + 12x^{2} + 2x + 8

Group, 3x^3+12x^2+2x+8  =(3x^{3} +12x^{2} )+(2x+8)factor out 3x^{2}in the first and 2 in the second group.

3x^{2} (x+4)+2(x+4)

Factor out common term x+4 by using distributive property.

polynomial 3x^{2} +2 is not factored since it does not have any rational roots.

(3x^{2} +2)(x+4)

The measure of an angle is seventeen times the measure of a complementary angle. What is the measure of each angle?
marysya [2.9K]
First, write an equation system for the problem
For example, x represents the first angle and y represents the second angle
An equation for "t<span>he measure of an angle is seventeen times the measure of a complementary angle" is
</span>∴ <span>x = 17y
The sum of complementary angle is 90</span>°. It can be written as<span>
</span>∴ x + y = 90°
<span>
Second, use subtitution method to find the value of x and y
Subtitute x with 17y
x + y = 90</span>°
17y + y = 90°
18y = 90°
y = 90°/18
y = 5°

Subtitute y with 5°
x = 17y
x = 17(5)
x = 85°

The measure of each angle is 5° and 85°
