Answer: 20
Step-by-step explanation:
Assuming your question is:
Z² - X² - XY X = -2, Y = 3, Z = -4
Substitute values
(-4)² - (-2)² - {(-2)(3)}
{(-4)(-4)} - {(-2)(-2)} - (-6)
(16) - (4) + 6
16 - 4 + 6
20
Answer:
-x +7
Step-by-step explanation:
Combine like terms.
Rewrite as 2x + (-3x) + 6 + 1
Combining your "x" terms gives you 2x + (-3x), or 2x - 3x = -1x or -x
Combining your integer terms gives you 6 + 1 = 7.
Recombining them gives you -x + 7.

For a triangle to be right angled the largest side squared must equal the sum of the squares on the other 2 sides ( Pythagoras theorem)
1. 101^2 = 99^2 + 20^2 so its is right angled
2. 28^2 is not equal to 26^2 + 12^2 - not right angled
3. 17^2 not euql to 14^2 + 6^2 - not
