Answer: 12. x =7 13. x =6

Step-by-step explanation:

Both angles in the triangle has to equal to each other because they are both equivalent.

Set both expressions equal to each other and solve for x.

12. 5x = 35 Divide both sides by 5

x = 7

13. 3x = 5x - 12 Subtract 5x from both sides

-5x -5x

-2x = -12 Divide both sides by -2

x = 6

Which shows one way to determine the factors of x^3 - 9x^2 + 5x - 45 by grouping ?

adoni [48]

You can group first two conjunctions and second two:
$x^3 - 9x^2 + 5x - 45=(x^3-9x^2)+(5x-45)$ .
In first brackets you have common $x^2$ and in second brackets common is 5:
$(x^3-9x^2)+(5x-45)=x^2(x-9)+5(x-9)=(x-9)(x^2+5)$ .
