Answer:
sum= -3 product=-4
Step-by-step explanation:
2x^2-2x+8x-8
2x(x-1)+8(x-1)
(2x+8)(x-1)
x=-4 x=1
All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
Answer:

Step-by-step explanation:
If that is a square, then all sides are the same. Therefore, it's a
by
shape. We'll use Pythagorean Theorem to find the diagonal.

Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!
