What is a difference of squares that has a factor of x+8? x2−4 x2−16 x2−64 x2−256

x² - 64

Step-by-step explanation:

Difference of squares: (x - a)²(x +a )²

With that, you have to have (x - 8) as a factor as well. Simply just multiply (x - 8) to (x + 8) and you get x² - 64 as your answer!

x=26°

Step-by-step explanation:

6x+(x-2)=180 (because together they form a straight angle which is 180°)

solve:

6x+x-2=180

7x-2=180

7x=182

x=26
