Answer:

2x2+3x-3

Step-by-step explanation:

The first thing you want to do is find all the X2"s and add those together and that looks like this 3x2+(-x2) which would be 2x2. Then you want to find all of the x's and add them together which looks like this -2x+5x which is 3x. Then you find all the whole numbers without a variable and that's 2-5 which equals to be -3.

Solve: + 12x = 9<br> Ox=3/5 :: 6<br> O x= 6 745<br> O=-6+ 745<br> O *=-6_315

Alex_Xolod [135]

Answer:

$x = \frac{3}{4}$

Step-by-step explanation:

$12x = 9$

Divide both sides by 12:

$\frac{12x}{12} = \frac{9}{12}$

Simplify the fraction:

$x = \frac{9}{12}$

Find the greatest common factor of the numerator and denominator:

$x = \frac{3.3}{4.3}$

Factor out and cancel the greatest common factor:

$x = \frac{3}{4}$

How would I simplify and solve for X in this trigonometric equation? (Radians)

Phoenix [80]

Answer:

Please, refer to the images below

Step-by-step explanation:

We need to solve for x in the equation

cos (x+ pi) ^2 = sin (x)

cos (x+ pi) = - cos(x)

(-cos (x)) * (-cos (x)) = sin(x)

cos(x) ^2 = sin(x)

We know that

cos(x) ^2 + sin(x) ^2 = 1

cos(x) ^2 = 1 - sin(x) ^2

1 - sin(x) ^2 = sin(x)

sin(x) ^2 + sin (x) -1 = 0

Let A = sin(x)

A^2 + A - 1 = 0

(solutions attached in picture 1)

This means that

x = arcsin(A)

The measures of the angles of a triangle are in the ratio of 2 : 5 : 8

andrezito [222]

Answer: The measures of all the three angles are 24 , 60 and 96

Step-by-step explanation:

$\\$ Since the measures are given in ratio form, the first thing is to find the total ratio, which is

$\\$ 2 + 5+ 8 = 15

$\\$ Recall that the sum of angles in a triangle is 180 ,so to calculate each angle , we have

$\\$ 2/15 x 180 = 24

$\\$ also , 5/ 15 x 180 = 60

$\\$ Finally, 8/15 x 180 = 96

$\\$ The triangle is obtuse , since it is having one angle greater than 90.

$\\$ It can not be acute because of the existence of 96 , for a triangle to be acute , all the angles must be less than 90 , and it can not be right triangle because there is no existence of 90
