Answer:
+2
Step-by-step explanation:
-(-2)
since: same signs gives the positive sign i.e + and different signs gives negative sign -
-×-2
=+2
Answer:
A
Step-by-step explanation:
To write the equation, find the slope of the line using the two points. Find the difference in y values over the difference in x values.
Write the equation using the slope m=3/2 and the point slope form.
This is the equation of the line. You can convert it to slope intercept form:
X² + xy - 2x - 2y
The first thing would be to break the polynomial up into pairs.
(x² + xy) + (-2x -2y)
Then you can factor them individually.
(x² + xy)
Both numbers have x in common, so you can factor it out and get
x(x + y)
Then you factor the other pair,
(-2x -2y)
Both numbers have -2 in them, so you can factor it out and get
-2(x + y)
Now your two pairs are
[x (x + y)] and [-2 (x + y)]
Notice that the two terms in parentheses are the same, so you can get rid of one and combine the two outside terms to get a final answer of
(x - 2)(x + y)
Answer:
14.8
Step-by-step explanation:
13^2 + 7^2 = 218
sqrt(218) = 14.76
