The answer is (x - 1)(3x + 5)


Let's substitute (x + 2) with a:
3(x + 2)² - 10(x + 2) + 3 = 3a² - 10a + 3 =
                                      = 3a² - 9a - a + 3 = 
                                      = 3a * a - 3a *3 - (a - 3) = 
                                      = 3a(a - 3) - (a - 3) =
                                      = (a - 3)(3a - 1)

Now, substitute a with x + 2:
(a - 3)(3a - 1) = (x + 2 - 3)(3(x + 2) - 1) = 
                     = (x - 1)(3x + 6 - 1) =
                     = (x - 1)(3x + 5)

PLEASE HELP QUICKLY<br> What is the value of y
Sidana [21]

Answer:

y= 8

Step-by-step explanation:

In a Triangle we know,

W+Y+X=180 degree

then,

(180-52)+(4y-4)+3y=180

or, 128+4y-4+3y= 180

or, 7y= 180- 124

or, y= 56/7

or, y= 8

hope you got it.

What is mZG?<br>Enter your answer in the box. <br><br>FGH<br>(x-5)°<br>(3x+24)°<br>x°​
lapo4ka [179]

Answer:

The angle for G is 121°.

Step-by-step explanation:

Given that total angles in a triangle is 180° so in order to find the angle of G, first, you hav eto find the value of x :

x + (x - 5) + (3x + 25) = 180°

5x + 20° = 180°

5x = 160°

x = 32°

Next, you have to find the angle of G :

G = 3x + 25

G = 3(32) + 25

G = 96° + 25°

G = 121°
